2dd5196267 egl: Set EGL_IMAGE_PRESERVED_KHR on DMABUF import
Otherwise drivers would be free to alter the buffer content. While no
driver is known to do so, it's probably good to make things explicit.

29ec2d2e20 screen-cast/src: Never dequeue pw_buffer's we refuse to record to
The DMA buffer paths vs MemFd paths differ slightly in when content is
recorded. This was in some places done by trying to record but bail if
the dequeued buffer had the wrong type. This is problematic for two
reasons: we'd update the timestamp even if we refused to record, making
the follow-up attempt fail, and we'd dequeue and queue buffers that
didn't get any content, meaning the receiving end would see empty
buffers potentially with only cursor updates.

Fix this by keeping track if a stream is DMA buffer able or not, and
don't attempt to record at all in the places we would previously require
DMA buffers. This avoids both issues: we don't dequeue/queue pw_buffers
that we refuse to record to, and we won't update the recorded timestamp
when we didn't intend to record to begin with.

different clips in a surface will substantially increase the redrawn

This should not result in excessive memory consumption as callers of

d643eb5c6f frames: Disable XDND support on the frame window
All X11 surfaces created by gtk4 claim to support XDND via the XdndAware
property. This was leading some clients, e.g. Qt, to consider the frame
window as drop target instead of the client window.

Avoid this issue by removing the XdndAware property again after gtk has
created the surface.

18be74edeb core: Fix map transitions for X11 windows on Wayland
We are attempting to show windows that do not yet have a
surface/buffer, this makes GNOME Shell avoid transitions
for these windows.

Since on Wayland X11 windows are also Wayland surfaces,
this check is also valid for these, and is thus made more
generic to also cater for these windows.

Eventually, meta_window_update_visibility() is called
when the surface gets its buffer, so the window can be
neatly animated.

cca07612b8 output: Check the EDID for the supported sink Colorimetry
Just like the HDR Metadata property the Colorspace property values only
indicate that the display driver supports signaling certain colorimetry.
It does not indidcate that the sink actually supports processing the
colorimetry. For this we have to look up the colorimetry support in the
EDID.

The default colorimetry is always supported. If we want bt.2020 we might
get either the RGB or YCC variant even if we ask for the RGB variant but
there is nothing we can do about it so let's just pretend it's a driver
issue.

a7a7933e03 wayland: Emit frame events in GSource after "empty" updates
Under certain conditions a stage-view update does not trigger a kms
update.

In such cases we still want the next update to run within the same
refresh cycle, as otherwise we'd waste the remaining time in the
current one.
At the same time we currently use the `after-update` signal for Wayland
frame events, which again may result in more "empty" updates -
creating an unthrottled feedback loop. This can trigger excessive
load both in the compositor as well as in clients.

Introduce a new GSource that is dispatched once per refresh cycle at
maximum per stage view and use it to emit frame events. Do so by
computing the time from when on we can be sure that an update resulting
from a client commit would certainly get scheduled to the next refresh
cycle.

Note: this only works on the native backend. Given that chances are
small that we hit the corresponding issue on e.g. the nested backend,
stick to the previous behavior there for now.

6b57ab8975 workspace: Only consider windows that should be showing as focusable
When selecting the default focus window, is_focusable() was not
considering the new conditions for whether a window should be shown or
hidden that were added to meta_window_should_be_showing() in 39942974.
As a result the default focus window could end up a window already
hidden or hidden once meta_window_flush_calc_showing() is called by
meta_window_focus() when focusing the default window. This would cause
meta_window_focus() to fail, which is an issue if it prevents us from
unfocusing a window when it is getting unmanaged.

2a600ac98e frames: Forward _NET_WM_STATE during frame initialization
Ensure the frame window is created at the right fullscreen state
before showing it and assigning it to the client window.

A peculiarity of this property on frame windows is that it is
typically single-handedly updated from the Mutter side, in synchronization
with client window state. It can only differ during creation, since
GTK still likes to apply its own state.

Also, the only relevant property seems to be _NET_WM_STATE_FULLSCREEN,
since the others are less relevant to the role of the frames client,
and get applied to the MetaWindow as a whole, instead.

50a37a7fc0 wayland/xdg-shell: Dismiss instead of destroy invalid popup
Destroying is insufficient as it doesn't end any popup pointer grab, if
the dismissed popup was the last. This would later hit an assert as the
popup grab is assumed to always have at least one popup in its chain.

697b99ee13 wayland/xdg-shell: Ignore reposition if popup was dismissed
If the popup was dismissed (i.e. has no MetaWindow anymore), it'll also
have no parent surface. With no parent surface, we'd try to fetch a
transaction from NULL and crash, but if we don't try if we were
dismissed, we won't reach here anyway.

f744acefee core: Create passive button grab on topmost Window
With the frames client, we do no longer handle events for the
frame window inside Mutter. This means we do not get events
"for free" to handle focus on a just clicked frame window.
This results in a background window not ending up focused if
clicked on its frame.

In order to fix this, make the passive button grab extend to
the frame window if a window has one. This brings back
focus-on-click behavior, while treating windows further as
a unitary surface.
