Application: kwin_x11 (5.18.5)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.8.0-50-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed: I was testing some wallpapers with komorebi, and to know which one I liked, I saw them before with vlc. When I close one of the live wallpapers that I saw with vlc, kde crashed and relog

The crash does not seem to be reproducible.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
