Bug 474925

Application: plasmashell (5.27.8)

Qt Version: 5.15.10
Frameworks Version: 5.110.0
Operating System: Linux 6.5.4-1-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.8 [CoredumpBackend]

-- Information about the crash:
I right clicked the konsole icon while it was open and pressed close, and immediately after, kwin wayland reloaded. Everything froze, then the taskbar disappeared and went black and reappeared.

This also occurred when I closed kate. 

Importantly, these issues usually occur after waking from sleep.

The crash can be reproduced sometimes.
