Description Saadin 2020-11-20 09:22:44 UTC
Application: kwin_x11 (5.19.5)

Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-29-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.10

-- Information about the crash:
- What I was doing when the application crashed:
Switching between virtual deskop using hot corners of screen. This usually happens when I do quick switches between multiple virtual desktops (but not always). It mostly happens when I'm on a desktop with firefox, then I switch to another desktops and quickly switch back.

- Custom settings of the application:

Compositor is enabled with opengl 2
Top left corner is set to view desktop grid
6 virtual desktops (2 rows)

The crash can be reproduced sometimes.
