Since commit 226afa24a - "Use Xwayland auto-terminate feature", the callback function shutdown_xwayland_cb() does not check for the autoclose-xwayland experimental feature anymore. As a result, when running nested or outside of systemd, gnome-shell/mutter would quit after 10 seconds unless some X11 window was mapped. But now that we rely on Xwayland's own terminate feature, there really is no need to use any xserver timeout function anymore. We do not need to keep track of X11 windows being created or unmapped, as again, Xwayland does all that for us at the client level. Remove all this code that we do not need anymore. fixes: 226afa24a - Use Xwayland auto-terminate feature Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2258>
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, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.

Git messages
Commit messages should follow the GNOME commit message
guidelines. We require an URL
to either an issue or a merge request in each commit. Try to always prefix
commit subjects with a relevant topic, such as compositor: or
clutter/actor:, and it's always better to write too much in the commit
message body than too little.
Default branch
The default development branch is main. If you still have a local
