When a device is removed from the seat the events that this device may have emitted just before being removed might still be in the stage events queue, this may lead a to a crash because: Once the device is removed, we dispose it and the staling event is kept in queue and sent for processing at next loop. During event processing we ask the backend to update the last device with the disposed device The device is disposed once the events referencing it, are free'd The actual last device emission happens in an idle, but at this point the device may have been free'd, and in any case will be still disposed and so not providing useful informations. To avoid this, once a device has been added/removed from the seat, we queue ClutterDeviceEvent events to inform the stack that the device state has changed, preserving the order with the other actual generated device events. In this way it can't happen that we emit another event before that the device has been added or after that it has been removed. Fixes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1345 |

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.

The coding style used is primarily the GNU flavor of the GNOME coding
style
with some minor additions such as preferring stdint.h types over GLib
fundamental types, and a soft 80 character line limit. However, in general,
look at the file you're editing for inspiration.
Commit messages should follow the GNOME commit message guidelines. We require an URL to either an issue or a merge request in each commit.
