Bug 473462

Application: plasmashell (5.27.7)

Qt Version: 5.15.10
Frameworks Version: 5.108.0
Operating System: Linux 6.4.9-1-default x86_64
Windowing System: Wayland
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.7 [KCrashBackend]

-- Information about the crash:
When I disconnect my external monitors and reconnect them later (by switching inputs on a KVM switch), plasmashell crashes. This issue does not only occur on my laptop (from which this bug report is sent), but also on my desktop with the same KVM switch and monitors.

The crash can be reproduced every time.

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