Description Riccardo Robecchi 2019-02-11 12:00:51 UTC 
Application: kwin_x11 (5.14.5)

Qt Version: 5.12.0
Frameworks Version: 5.54.0
Operating System: Linux 4.20.6-xanmod4 x86_64
Distribution: KDE neon User Edition 5.13

-- Information about the crash:
- What I was doing when the application crashed:

I opened a video using VLC, then tried to quit VLC when the screen froze. I was still able to move the mouse cursor around, but everything had become unresponsive. I tried to open the same video again, but was not able to reproduce the behaviour.

The crash does not seem to be reproducible.

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