-- Information about the crash:
As https://bugzilla.redhat.com/show_bug.cgi?id=2385954#c0 explains, I extended System Setttings, horizontally, quite far past the boundaries of the display. Initially, the content became stretched and corrupted. Then, it became black. Then, the window decorations became black (and squared), with solely the shadow remaining as it should. Then, it crashed. Other attempts have also crashed the XWayland compositor.

The crash can be reproduced every time.
