-- Information about the crash:
I unlocked my desktop session, and plasmashell crashed with the included backtrace. I am running a multimonitor setup with amdgpu.

bug #487699 says "We believe this is fixed in Qt, please reopen if an issue persists with Qt 6.8". I am using Qt 6.8 and the bug persists.

The crash can be reproduced sometimes.
