Bug 466631

Application: plasmashell (5.27.1)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 5.19.0-32-generic x86_64
Windowing System: Wayland
Distribution: KDE neon 5.27
DrKonqi: 5.27.1 [KCrashBackend]

-- Information about the crash:
I've tried switching between display configurations using the built in "For only this specific display arrangement" in the display configuration by powering off one of my monitors and it will sometimes crash the plasmashell. It seems like changing the latency in the compositor causes it to crash a lot less.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
