Bug 414434

Application: kwin_x11 (5.17.3)

Qt Version: 5.13.2
Frameworks Version: 5.64.0
Operating System: Linux 5.3.12-zen1-1-zen x86_64
Distribution: Arch Linux

-- Information about the crash:
- What I was doing when the application crashed:
I was using TTY, then after going back to graphical logged in session, the KWin was crashed. That occurs aways when switching to full screen with a different resolution 
- Unusual behavior I noticed:
Some sttutering when, for example, scrolling pages on any application. Then, after some miliseconds, the stuttering go away and all stay fluid

The crash can be reproduced every time.

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