Application: kwin_x11 (5.16.5)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-24-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:
	When I wake my computer after suspending, there is some graphical glitches in icons's text in desktop. So I run these commands (got it from internet):
	/usr/bin/kquitapp5 plasmashell; plasmashell > /dev/null 2>&1 & disown; sleep 2; exit
	In order to reset plasmashell and fix the glitches. It works!
- Unusual behavior I noticed:
	Nothing except a window telling me that KWin has crashed right after I run the commands.

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