Application: plasmashell (5.23.5)

Qt Version: 5.15.3
Frameworks Version: 5.90.0
Operating System: Linux 5.13.0-27-generic x86_64
Windowing System: Wayland
Distribution: KDE neon User - Plasma 25th Anniversary Edition
DrKonqi: 5.23.5 [KCrashBackend]

-- Information about the crash:
When I drag the screen edges button, Plasma spontaneously crashes.
Sometimes, it happens, sometimes, it doesn't.
I'm not sure if this happens only on Wayland, but that was where the bug was encountered.

The crash can be reproduced sometimes.

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