Description bertil.bonus 2021-10-16 09:07:37 UTC
Application: plasmashell (5.23.0)

Qt Version: 5.15.3
Frameworks Version: 5.87.0
Operating System: Linux 5.11.0-37-generic x86_64
Windowing System: Wayland
Distribution: KDE neon User - Plasma 25th Anniversary Edition
DrKonqi: 5.23.0 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I had previusly corrected the panel i a Wayland session. After logging in on a X11 session the panel was gone. To try and get my panel back I logged beck into a wayland session. Adjusting the panel position to screen edge the crash occured. 

Enter edit mode -> screen edge. Then crash.

- Unusual behavior I noticed:
Screen layouts are supposed to be preserved wayland / X11 but they are not.
Wayland session "sluggish". No appearant reson.

The reporter is unsure if this crash is reproducible.

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