From a2789eef9adbb8fb5e3ba1c278041996fa69eedc Mon Sep 17 00:00:00 2001 From: Robert Mader Date: Mon, 4 Nov 2019 11:45:13 +0100 Subject: [PATCH 2/3] surface-actor-wayland: Do not send frame callbacks if the actor is obscured `meta_surface_actor_is_obscured` implies that the actor got successfully culled out and nothing of it will get painted. This includes that there are no clones, no effects etc. In this cases we don't want to send frame callbacks, thus avoiding unnecessary client work. https://gitlab.gnome.org/GNOME/mutter/merge_requests/918 --- src/compositor/meta-surface-actor-wayland.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/compositor/meta-surface-actor-wayland.c b/src/compositor/meta-surface-actor-wayland.c index 1c933d554..e16f53ff2 100644 --- a/src/compositor/meta-surface-actor-wayland.c +++ b/src/compositor/meta-surface-actor-wayland.c @@ -115,7 +115,8 @@ meta_surface_actor_wayland_paint (ClutterActor *actor) { MetaSurfaceActorWayland *self = META_SURFACE_ACTOR_WAYLAND (actor); - if (self->surface) + if (self->surface && + !meta_surface_actor_is_obscured (META_SURFACE_ACTOR (actor))) { MetaWaylandCompositor *compositor = self->surface->compositor; -- 2.24.1
