Application: plasmashell (5.17.1)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-19-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed:
Closing a Firefox (Nightly running on Wayland backend) window

- Unusual behavior I noticed:
The firefox window was glitching (garbled display when maximized)
Other windows on the desktop (including DRKonqi) are also glitching

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
