Marco Trevisan (Treviño) 9f98743cfc surface-actor-x11: Bind the surface actor resources to window actor life 
X11 actors need to release the server data (pixmap and damage) before the
display is closed.
During the close phase all the windows are unmanaged and this causes the window
actors to be removed from the compositor, unsetting their actor surface.

However, in case a window is animating the surface might not be destroyed until
the animation is completed and a reference to it kept around by gjs in the shell
case. By the way, per commit 7718e67f all window actors (even the animating
ones) are destroyed before the display is closed, but this is not true for the
child surface, because the parent window will just unref it, leaving it around
if reffed somewhere else. This is fine for wayland surfaces, but not for X11
ones which are bound to server-side pixmaps.

So, connect to the parent MetaWindowActor "destroy" signal, releasing the x11
resources that implies detaching the pixmap (unsetting the texture) and removing
the damages.

Mutter

Mutter is a Wayland display server and X11 window manager and compositor library.

When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.

When used on top of Xorg it acts as a X11 window manager and compositing manager.

It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.

Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.

Mutter is used by GNOME Shell, the GNOME core user interface. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
