Severity: crash
Priority: NOR

Operating System: Linux 5.4.0-62-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:
Disabled second monior from settings. Then enable. There is no primare monitor
setting so I did this to move the application menu bar.
- Custom settings of the application:
The compositor settings page said that there had been a crash. I tried to
enable opengl 3.1. After thar crash and reboot. Not sure if that has anything
to do with this crash. Now settings sais opengl 3.1 accurate.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
