Description gregoryarapis 2021-05-11 17:48:02 UTC 
Application: plasmashell (5.21.5)

Qt Version: 5.15.2
Frameworks Version: 5.82.0
Operating System: Linux 5.12.2-arch1-1 x86_64
Windowing System: X11
Drkonqi Version: 5.21.5
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I moved a widget from my 2560 x 1080 hdmi monitor to my 1024 x 720 vga(through display port) and caused Plasma to crash. The first time it recovered itself after a black screen and my system was back on but my widget was gone. 
I did it again to see if I could replicate it and it crushed again this time plasma didn't recover.

- Custom settings of the application:

The widget was the system monitor one. The first system monitor was for each CPU core usage the next was for each CPU core frequency

The crash can be reproduced every time.

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