SUMMARY
Stopping monado service on a KDE 6 plasma desktop crashes xwayland when the drm lease is released on a wired headset.

This may also occur with steamvr but I have not tested that yet.

STEPS TO REPRODUCE
1. Start monado with a wired HMD connected to PC and some xwayland apps open
2. Stop monado
3. xwayland will crash

OBSERVED RESULT
xwayland crash

EXPECTED RESULT
xwayland should survive a drm lease releasing

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 6.0.2
(available in About System)
KDE Plasma Version: 6.0.2
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2

ADDITIONAL INFORMATION
Appears to have regressed from plasma 5, my Gentoo box still on 5 does not produce this behavior
Coredump included below

I have narrowed this down further
Qt5 application windows open seem to instigate this crash.

Steam and Corectrl being two.

If you stop the service while a qt5 application is open xwayland will crash.

This is very likely related to a ticket being tracked in xwayland.

Definitely sounds like it. If it turns out not to be the same though, please make a separate issue for Xwayland - its crashes have to be fixed in its code base.
