Description Kristen McWilliam 2024-07-15 16:09:18 UTC 
Application: plasmashell (6.1.1)

Qt Version: 6.7.2
Frameworks Version: 6.3.0
Operating System: Linux 6.9.7-200.fc40.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 40 (KDE Plasma)"

-- Information about the crash:
The crash seems to happen in 2 scenarios:

- One of the attached displays is turned off, and goes in to a sleep mode where it is momentarily seen as disconnected
- I press a hotkey that runs a script, which changes the enabled displays using kscreen-doctor

The crash can be reproduced sometimes.
