Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2527>
When we change the privacy screen, we added a result listener to the KMS
update object to notify the upper layer about the privacy screen state
change. This was slightly awkward as one might have changed the state
multiple times for a single update, thus it was necessary to remove any
old result listeners to an update before adding a new one.
Doing this will not be possible when updates are fully async and managed
by the KMS impl device.
To handle this, instead make the post-commit prediction notify about
changes that happens in response to a successfully committed update. We
already predicted the new privacy screen state, so the necessary change
was to plumb the actual change into a callback which emits the signal if
there actually was a privacy screen change.
This will then be communicated via the same signal listener that already
listens to the 'resources-changed' signal.

The name had a bit conceptual conflicts with MetaKmsUpdate, as it shared
its namespace but had no relation to it. Fix this by renaming it
MetaKmsResourceChanges (and the corresponding META_KMS_UPDATE_CHANGE_*
to META_KMS_RESOURCE_CHANGE_*). The term "resource" is used since that's
already used in the signal, and the fact that the changes partly comes
from changes in the DRM resource as retrieved by drmModeGetResources.

With this header we can set a flag to signal that the whole buffer is
corrupt and should be ignored. With this we can cater to all cases:
* Window buffer fine, but cursor broken:
Use the spa_meta_cursor properties like id or offset accordingly
* Window buffer broken, but cursor fine:
Use the chunk flags
* Both are broken / the dequeued buffer is not usable
Use the spa_meta_header flag
Additionally clients can now check if a buffer contains spa_meta_header
data and can thus only check for the new or the old behaviour.

PipeWire supports flags to signal a corrupted buffer. We should use the
flag SPA_CHUNK_FLAG_CORRUPTED for `chunk->flags` instead of setting
`chunk->size = 0` since the size isn't well defined for arbitrary dmabufs
and should be set to 0.
Sadly clients like obs are using a chunk size of 0 to decide if a buffer
should be imported. Thus we should offer both until clients are using
the flag.

When building the list of formats to be sent as part of the scanout
tranche, avoid requiring modifier support by the DRM driver for
formats relying on implicit modifiers (DRM_FORMAT_MOD_INVALID).
Specifically, the previous check required the DRM driver to have
advertised some modifier support for the given format in its
IN_FORMATS KMS plane property, regardless of modifier it was. If it
hadn't, the format was left out of the list of formats to be sent
in the scanout tranche.
When no formats remained to be sent in the scanout tranche, the
tranche simply wasn't sent.
This resulted in the scanout tranche never being sent for GPUs where
modifiers aren't supported. In those cases, no formats are advertised
using the IN_FORMATS property, and thus the list of formats to be sent
in the scanout tranche remained empty.
Since Mesa doesn't use scanout-compatible buffers for native Wayland
clients unless specifically requested to do so using the "scanout"
tranche flag, it effectively means that direct scanout of native
Wayland clients wasn't supported for GPUs without modifiers support.
Sending a tranche with formats paired with the implicit modifier
(DRM_FORMAT_MOD_INVALID) is both allowed by the protocol and is
already done by default for GPUs with modifiers support, unless the
experimental support for explicit modifiers is enabled in Mutter.
So instead of requiring modifiers to be supported for each format
being evaluated for the scanout tranche, when processing formats
which rely on implicit modifiers, only check if the format in
question is supported by the DRM driver for scanout on the primary
plane.

While the check for `clutter_actor_has_mapped_clones` clearly indicates
an intention to take clones into account, the following code
does not do so, likely because it predates the introduction of
`clutter_actor_is_effectively_on_stage_view()`.
Switch to that newer API in order to take clones into account. This
avoids unnecessary `wl_surface_send_enter()` and `wl_surface_send_leave()`
events when entering the overview, reducing client work.
This also avoids unnecessarily allocating a `cairo_region_t`.

`clutter_actor_set_child_at_index()` is far from a no-op, even if

Unparenting the surface actor when the subsurface object is destroyed
has several issues:
- subsurface actors can be unparented while a close animation is
still ongoing, breaking the animation for e.g. Firefox.
- adding and removing the actor to/from the parent is not handled in
one place, making the code harder to follow.
- if the destroyed subsurface had children of its own, they potentially
stick around until a surface-tree rebuild. This makes the Firefox
hamburger menu not close with the "compositor" backend.
Move the unparenting back to
`meta_window_actor_wayland_rebuild_surface_tree()` and instead just
notify the parent of a state change, if it still exist. This will ensure
a correct mapping between the subsurface node tree and the flat surface
actor list. In case of the closing animation the parent will already be
removed and the call is skipped.

Since b443bd42ac, we unmanage a wayland window when clearing its
transient parent. That's to make sure that xdg-foreign doesn't
leave the dialog around after the imported surface was destroyed.
While that behavior is sound, it is problematic to implement it
by unmanaging the window, as that happens entirely behind the
client's back.
Instead, send a close event for the window. Unless the client has
good reasons, it should honor the request. (And if it has good
reasons - like unsaved work - then effectively hiding the window
from both the user and client is probably not the best idea anyway).

Not all windows can be minimized: X11 clients can disable the
functionality, and so do we for windows that aren't shown in
the alt-tab popup or the shell overview, so there would be no
way of getting them back.
While we make sure that we respect that ourselves (keybinding,
window menu, etc.), we don't guard meta_window_minimize(), so
clients or extensions can still minimize a window that isn't
supposed to be minimized.
That can lead to all kinds of issues, from the hidden window
being lost (as far as users are concerned) to a crash when
the minimzed window has a transient parent.
Just add an explicit check to make sure the unexpected doesn't
happen after all, and print a warning if it does.

The cursor rendering code path used by the screen cast code relies on
the cursor tracker machinery to determine where to blit the cursor
texture, but at the moment the cursor position invalidation is behind
a check for whether the shell is using a Wayland backend. (This code
path used to be Wayland-specific before 00cbcb7ba1 but has been
backend-agnostic since).
This commit removes the check for a Wayland compositor, allowing
cursor drawing to function correctly on X11 when screen casting in

The test case checks that the stage views of hidden actors are
not updated when the views of the visible outer parent change.
The check for the outer parent's updated stage views currently
relies on ClutterFixedLayout not excluding hidden children in
its size request: As the container doesn't contain any visible
children at that point, its size would change to 0x0 and end
up on no stage view (rather than the assumed two).
Avoid that oddity by giving the outer container a fixed size,
so that the visibility of its child doesn't affect the test
when we fix ClutterFixedLayout.

The test aims to test that trying to fetch X11 clipboard content after
Xwayland went away doesn't cause issues. What happens though is that
sometimes the clipboard content doesn't have time to settle (i.e. fetch
mime types etc) before Xwayland gets terminated, which causes flakyness.
Fix this by waiting for the compositor side clipboard owners to finish
setting up before continuing.

The pixel clock determines how fast pixels can be processed. When adding
non-native common modes, avoid adding modes that exceed the max pixel
clock frequency of the native modes. Avoiding these avoids potential
mode setting failures where the GPU can't handle the modeline since the
configured pixel clock is too fast. This replaces the "bandwidth" check
which used the number of pixels and refresh rate, which wasn't enough to
avoid incompatible modes.

'screen-cast/monitor-src: Use clutter_stage_paint_to_buffer'
(6c818cd8d5) made the non-dma-buf path use
clutter_stage_paint_to_buffer() to avoid running into direct scanout
issues. At a glance, the dma-buf paths didn't have the same issue since
it explicitly handled dma-bufs by blitting them.
What it also did was move the recording to an idle callback, to avoid
paint reentry issues. A side effect of this, however, is that it also
broke the dma-buf paths, as they rely on the back buffer existing, and
the stage view direct scanout already being setup, which it isn't in an
idle callback.
Fix this by using the dma-buf variant of
clutter_stage_paint_to_buffer(): clutter_stage_paint_to_framebuffer().
This has some negative performance impact, but we can't use
cogl_blit_framebuffer() when using an idle callback for recording.
Potential performance improvements to make things work more as they did
before is to enhance 'cogl_blit_framebuffer()' a bit, making it a vfunc
that could be implemented by MetaOnscreenNative. A flag to say whether
to look at the back or front buffer would let MetaOnscreenNative know
whether to use the already committed-to-KMS buffer, or the current back
buffer.

Add `sync_effects_completed()` and `verify_view()` in
order to allow Wayland test clients to trigger verifications
and add convenience functions to use them to client-utils.
Notes:
- `sync_effects_completed()` works in two stages in order
to ensure it doesn't race with window effects. By the time
`sync_effects_completed()` is processed, an effect could
already have ended or not yet been scheduled. Thus we
defer a check for pending effects to the next paint cycle,
assuming that by then they should have been scheduled.
- `meta_ref_test_verify_view()` internally triggers the
`paint` signal for the stage which is why it can not be run
in the after-paint signal handler.

Our internal interpretation of output transforms is not in line with
the Wayland spec. Wayland describes them as the transform that a
compositor will apply to a surface to compensate for the rotation
or mirroring of an output device - counter-clockwise.
Mutter in turn interprets it the other way around. One could
argue it does the same but clock-wise - or it interprets the transform
from the viewpoint of the content, not the device.
In either way, the difference is that 90 and 270 degree values are
switched. Thus swap these accordingly when we translate from
`WL_OUTPUT_TRANSFORM` to `META_MONITOR_TRANSFORM`.

The Xwayland server can go away at any time; when this happen we might
have a test client running, and for it to tear down more nicely, make
sure to avoid trying to clean up X11 resources on the old X11 display.

Xwayland can disappear at any time, for example during a new_async() or
read_async() call. When we eventually finalize the stream, the X11
display it was created for is gone, thus can't clean up the X11
resources. Handle this by making the MetaX11Display pointer a weak
pointer, and ignore cleaning up if it disappeared. This is fine since
the X11 server it created those resources one is gone already.

The code is already trying to avoid creating new laters when there
already is one for the queue type, but this wasn't working because the
ID of the later was never stored after creating a new one. This would
then result in as many laters as meta_display_queue_window() was called
and all of them would run the handler function, even if only the first
one had a non-empty window queue.
Similarly this was causing the later to not be removed if the window
queue got empty after meta_display_unqueue_window().

Currently the signal is getting emitted accidentally, because even when
removing a window from the queue, the later handler of that queue will
still get run due to a bug. This bug is going to get fixed in the next
commit, but some things might depend on the signal getting emitted when
the visibility of a window has changed.
This change affects the behavior in two ways. First the signal is now
emitted immediately rather than from an idle. And second it now
correctly includes the window in the should_show or should_hide list.

The compositor currently only updates the topmost window actor that is
visible to it after stacking changes. The visibility of a window actor
to the compositor however might only change via the display idle queue
after the stacking changes. This could then lead to the topmost window
actor being assumed to be NULL on Wayland after switching from an empty
workspace or when opening the first window on an empty workspace. The
result of this is direct scanout being disabled in these cases.
To fix this also trigger the update when the visibility of windows

Some windows span the entire screen but still use transparency, such as
the desktop window of Nemo. When these windows were used for direct
scanout, the transparent areas would turn black and nothing else would
be rendered.

the window actor itself has to be checked, because its opacity might
have been changed via _NET_WM_WINDOW_OPACITY.

The monitors settings such as the privacy screen property is propagated
to the monitors via kms updates, however during initialization and
on monitors changes, we end up clearing the pending KMS updates because
such settings are added to the queue before the backend has fully

pending updates, including the one we've just planned.
To avoid this, move settings applications after we've both initialized
the backend and notified it about changes.
Also avoid to try set the settings during actual initialization, but

Prior to 'compositor: Destroy actors when unmanaging', window actors
were destroyed when the compositor object was destroyed, long after the
windows were unmanaged, however, when this instead changed to happen
when unmanaging, with the original goal to avoid having these actors try
to interact with the disposed MetaCompositor instance, it caused an
issue where window actors would be indirectly destroyed as a side effect
of their parents being destroyed, which caused some fallout in the logic
handling window-close animation tracking, which relies on
meta_window_actor_queue_destroy() being called before a window actor is
actually destroyed.
Fix this by unmanaging windows before unmanaging the compositor.
From an X11 point of view, this should be harmless, since all it really
do is call XCompositeUnredirectSubwindows().
For the native backend and the common behavior, all unmanaging the
compositor instance does is destroy clutter actors, so doing so after
window actors were already cleaned up should not be a problem, as this
was the case before too.

When an X11 window becomes an all-workspace window its `workspace` is
set to NULL before `meta_window_x11_current_workspace_changed()` is
called. The latter then checks for `workspace` being NULL (which also
happens when unmanaging) and then returns early. So this does not update
`_NET_WM_DESKTOP` to 0xFFFFFFFF. Instead it remains at the workspace the
window was on before. This was causing programs like `wmctrl` to switch
to this old workspace when activating such a window.
Fix this by checking if the window is unmanaging instead.

Unfortunately we cannot do this generically since the target of the
button/touch press does matter, e.g. tapping on the OSK, or clicking
the IBus candidates window. These situations should not trigger a

So be more selective about the situations where button/touch presses
trigger an IM reset, in the case of ClutterText these are still clicks
inside the actor, for Wayland's text-input it is when clicking the
surface that has text_input focus.
For all other situations where clicking anywhere else might make
sense to trigger an IM reset are covered by the focus changing paths,

With Xwayland on demand, a number of maintenance X11 applications need
to be run first, before Xwayland starts accepting requests from the
normal clients, as soon as the WM_S0 selection is acquired by mutter.
On startup, mutter also sets a number of X11 properties that can be
queried by X11 clients.
Unfortunately, mutter acquires the WM_S0 selection before setting those
properties, so mutter and the first regular X11 client will race on
startup.
As a result, the X11 properties set by mutter on startup may not be
available to the very first X11 client when Xwayland starts.

Currently, meta_xwayland_shutdown_dnd() is called from the handler
on_x11_display_closing() triggered from the signal "x11-display-closing"
hooked up from meta_xwayland_init_display().
Once the signal has been triggered, on_x11_display_closing() removes the
signal handler, disconnecting from the signal.
As meta_xwayland_init_display() is called from meta_display_new() which
is issued only once, the signal handler is not restored again.
As a result, meta_xwayland_shutdown_dnd() is not called anymore after
Xwayland has been restarted, but meta_xwayland_init_dnd() will check and
assert that the manager's DND object is NULL.
Basically, restarting Xwayland more that once will trigger an assertion
failure in mutter. That's even more of a problem with autoclose-xwayland
where Xwayland is expected to terminate when there is no meaningful X11
client remaining, which can happen multiple times during the lifetime
of a user session.
To make sure that meta_xwayland_init_display() is called for every new
instance of Xwayland, simply keep the signal hooked in place by not
disconnecting it when triggered.

We use meta_workpace_focus_default_window() to sync the input focus back
to a window after it was on shell UI, this is not really necessary on
Wayland, but it is on X11. What this function does internally is ask
MetaWindowStack about the topmost window and focus+raise that window.
In gnome-shell we set the input focus to the default window every time
the key-focus changes to NULL (see shell-global.c ->
sync_stage_window_focus()). Now when closing the alt-tab switcher and
activating a window while there's an always-on-top window on the
workspace, meta_workspace_focus_default_window() will focus that
always-on-top window right after closing the alt-tab switcher, making it
impossible to focus another window using alt-tab.
To fix this, make meta_workspace_focus_default_window() check if there's
an existing focus_window first, if there is, use that, and if there
isn't, resort to just focusing the topmost one.

We use get_window_for_event() to check whether an event happened on top
of a window or on top of shell UI to decide whether to bypass delivering
the event to Clutter. In case of crossing events though, we can't just
use the device actor to determine whether to forward the event to
Clutter or not: We do want to forward CLUTTER_LEAVE events which
happened on top of shell UI. In that case the device actor is already a
window actor (the pointer already is on top of a window), but the shell
still needs to get the LEAVE crossing event.
Since the event source actor got removed from the detail of
ClutterEvent, the context we're looking for (which actor did the pointer
leave) is now the target actor that the event gets emitted to. Since the
last commit, we also made event filters aware of this context by passing

Prior to 67033b0a mutter was accidentally including sizes for
configurations that were just focus state changes. This was not leading
to any known problems on the client side, but it was causing issues in
mutter itself when detecting whether a resize originated from the client
or the server.
Not including sizes in focus change configurations anymore however
revealed a bug in gtk. It was storing the window size when in a fixed
size mode (tiled/maximized/fullscreen), but not on any other server side
resizes. It was then restoring this stored size whenever there was a new
configuration without a size while in floating mode, i.e. the focus
change configurations generated by mutter after 67033b0a.

When a drag and drop occurs from an X11 client to a Wayland native
client, mutter uses an internal X11 window as a peer for the DnD drop
site.
That internal X11 window is moved and resized to match the Wayland
native windows as the drag destination moves.
When moving from one Wayland native window to another Wayland native
window, the same X11 window is used, and as a result no DND enter/leave
events is emitted.
In that case, the drop may occur on the wrong Wayland native window,
because no new XdndEnter/XdndLeave event were emitted.
To avoid that issue, use a pair of X11 windows instead of just one and
alternate between the two when repicking a new drop surface, so that
moving from a Wayland surface to another will always generate the
expected enter/leave events that we rely on.

When generating the action label, we expect both directions of these
features to have consistent settings (either both get a keycombo, or
they don't) or these just return NULL altogether.
Since one of the directions has an action associated, this is
misleading, so be more lenient at the time of generating the action
label.

If we happen to handle a CLUTTER_TOUCH_BEGIN without a corresponding
CLUTTER_TOUCH_END at MetaWaylandTouch, we would still attempt to
reuse the older MetaWaylandTouchInfo, resulting in an assert triggered
as there is a stale touch reference on the previous surface.
Warn in place and create a new touch info struct to still fix the
broken surface accounting, instead of finding out the hard
way after the surface is destroyed. The assert is preserved to ensure
the accounting does not sneakily break anymore/further.

It passes a MetaLogicalMonitor, which isn't introspected right now, so
skip it completely. The entry point to the UI is handled via
MetaDisplay, so it isn't needed.
This fixes the following warning:

Structure tests in a list of dictionaries, instead of requiring each
test to have its own executable(...) and test(...) statement. The
intention of this is to make it easier to add more test cases.

It already was built into it without any symbols exported, but also
duplicated in test cases that used it. Make it so that the built in
functions are exported, with prefixes, and make all tests use the
exported functions. While at it, make things go via MetaContext or
MetaBackend depending on how early in initialization things are run.

We update some details like the last used device and pointer visibility
from events, but this is done inconsistently on X11 since the
ClutterEvents are created and pushed from an additional place.
Make these updates happen on a private call, that will be called from
these places in X11.

Even though it's great that XI2 has an event to notify about device
changes, this is something we can let the MetaBackend code handle
consistently for all backends, since looking for the source device
works everywhere.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/285>
Instead of relying in the device being updated from different parts of our
machinery for different backends, hook this up to our own event dispatching.
This will allow dropping all other places where this is done.

We create a cursor renderer per device for those at
meta_seat_native_handle_event_post() with PROXIMITY_IN events, but
the MetaWaylandTabletTool handles the event before that, and goes
with a NULL cursor renderer.
Make MetaBackend::get_cursor_renderer() on the native backend create
those cursor renderers on demand, and only handle PROXIMITY_OUT in
handle_event_post() to dispose those. This makes MetaWaylandTabletTool
happily get a cursor renderer again.

We now only enable DMA buffer based PipeWire screen casting if a
format/modifier has been negotiated. This practically means a consumer
is aware about what is needed, and we should not try to predict that it
uses the DMA buffer the right way (i.e. not mmap:ing directly).
However, in case we're not hardware accelerated, we never want to
attempt to use DMA buffer screen sharing, as we want to avoid
compositing into a DMA buffer on such hardware as doing so can be very
slow.

meta_window_(un)queue() was implemented with global arrays in window.c
that managed MetaLater handle IDs and lists of window queues. In order
to rely less on scattered static variables and making it clearer that
we're dealing with per display window management and not something
specific to a single window, move the window resize/calc-showing queue
management to MetaDisplay.

It's still used by e.g. GNOME Shell to produce fallback icons for X11
applications that doesn't come with a .desktop file. Geometry stays in
the generic class because it's used for minimize animations and is
configured by the panel (e.g. the one in gnome-shell-extensions).

The comments in this function tells a story of C programmer self
reflecting about data types and Perl. While that can be nice, the rest
consisted mostly of repeating what the code line below did, with the end
result being that the function didn't fit on screen, resulting in worse
readability overall.

When handling lid state, we used to update the idle time right after
opening the lid. This behavior changed in commit 14b6c8780d due
to a typo/thinko, "if (lid_is_closed)" used to be an early return
condition before updating idle time, now it only updates in that
case.
Restore the original behavior, since this idle time update is key
in having gsd-power light up the display again, this presumably
fixes situations that required extra "light up" hints after suspend.
What it does surely fix is "ninja test" in g-s-d against recent
mutter, since the behavioral change induced a test timeout there.

The `ensure_x11_unix_perms` function tries to detect systems on which
/tmp/.X11-unix is owned by neither root nor ourselves because in that
case the owner can take over the socket we create (symlink races are
fixed in linux 800179c9b8a1e796e441674776d11cd4c05d61d7). This should
not be possible in the first place and systems should come with some way
to ensure that's the case (systemd-tmpfiles, polyinstantiationm …). That
check however only works if we see the root user namespace which might
not be the case when running in e.g. toolbx.
This change relaxes the requirements such that in the root user
namespace we detect and abort if a vulnerable system is detected but
unconditionally run in toolbx.

Add some debug logging that allows checking whether we're using DMA
buffers for screencasting or system memory buffers. This can be useful
for debugging screencasting performance and CPU usage.

With the ability to query the renderer for DMA-BUF support we can

Returns TRUE if the active renderer backend can allocate DMA buffers.
This is the case hardware accelerated GBM backends, but FALSE for
surfaceless (i.e. no render node) and EGLDevice (legacy NVIDIA paths).
While software based gbm devices can allocate DMA buffers, we don't want
to allocate them for offscreen rendering, as we really only use these
for inter process transfers, and as buffers allocated for scanout
doesn't use the relevant API, making it return FALSE for these solves
that.

There may be situations where we may stack a ClutterGrab on top of a
wayland popup's. Since ClutterGrab should win over client grabs, we
mostly correctly figure out that it should start doing
bypass_wayland=TRUE and bypass_clutter=FALSE while the ClutterGrab
holds, however the late checks for the MetaDisplay event route can
still toggle bypass_clutter on, resulting in neither handling events.
This check for wayland popups in the display event route should just
enforce wayland handling if wayland is meant to be receiving events,
so ensure these don't mix together.

Wayland event processing and WM operations are themselves outside the
ClutterGrab loop so far. Until this is sorted out, these pieces of
event handling have got to learn to stay aside while there is a
ClutterGrab going on.
So, synchronize foci and other state when grabs come in or out, and
make it sure that Wayland event processing does not happen while
grabs happen.

Since we want these accessed from bindings this must be a boxed
type. This has the side effect of making ClutterGrab a refcounted
object, since we want to avoid JS from pointing to freed memory
and maybe causing crashes if misusing the object after dismiss.

This is (luckily!) unused, and it's inconvenient to have a toggle to

The experimental feature "autoclose-xwayland" requires a couple of
prerequisites:
1. Be able to (re)start Xwayland on demand, i.e. with systemd
2. Xwayland must support the terminate delay
Add a warning message if "autoclose-xwayland" was requested but any of
those prerequisites is not met.
