Description fabiodanielreis 2020-03-12 15:19:21 UTC

Application: kwin_x11 (5.17.5)

Qt Version: 5.13.2
Frameworks Version: 5.67.0
Operating System: Linux 5.5.6-201.fc31.x86_64 x86_64
Distribution: Fedora 31 (KDE Plasma)

-- Information about the crash:
- What I was doing when the application crashed:
Creating a new virtual desktop
- Custom settings of the application:
I think the issue started after setting speciall applications settings for Slack and Thunderbird. I set the 'Desktop' option to 'All Desktops' (Force)

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
