Description mynamewastaken 2024-06-21 23:41:46 UTC 
Application: plasmashell (6.1.0)

Qt Version: 6.7.1
Frameworks Version: 6.3.0

DrKonqi: 6.1.0 [CoredumpBackend]

-- Information about the crash:
I have a kvm switch (usb only - no video), but my monitors have multiple inputs. I login to my personal desktop (or sometimes wake from sleep), use the desktop a bit, then switch monitor inputs to my work laptop.
When i swap the inputs back to my desktop i get the crash dialog for plasma.

The crash can be reproduced sometimes.

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