This checks that an unmapped but created Wayland window correctly handle monitor changes. This is specifically added to test an edge case causing a crash with the following backtrace: ``` ... 4) 0x00007ffff78a2a6b in g_assertion_message_expr () 5) 0x00007ffff7defd5b in meta_window_update_for_monitors_changed () at ../src/core/window.c:3745 6) 0x00007ffff7899758 in g_slist_foreach () at ../glib/gslist.c:885 7) 0x00007ffff7dbe562 in meta_display_foreach_window () at ../src/core/display.c:3185 8) 0x00007ffff7dbe5fd in on_monitors_changed_internal () at ../src/core/display.c:3210 9) 0x00007ffff796f4ff in g_closure_invoke () at ../gobject/gclosure.c:830 10) 0x00007ffff7981316 in signal_emit_unlocked_R () at ../gobject/gsignal.c:3740 11) 0x00007ffff7987699 in g_signal_emit_valist () at ../gobject/gsignal.c:3495 12) 0x00007ffff7987bc2 in g_signal_emit () at ../gobject/gsignal.c:3551 13) 0x00007ffff7d89915 in meta_monitor_manager_notify_monitors_changed () at ../src/backends/meta-monitor-manager.c:3517 ... ``` Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2554> |

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 of 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
checkout under the old name, use:
git checkout master
git branch -m master main
git fetch
git branch --unset-upstream
git branch -u origin/main
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
