Description Błażej Szczygieł 2025-10-26 12:57:30 UTC

SUMMARY
It works, but I see error messages in logs every second when virtual screen is added in screen share dialog (e.g. in OBS).

STEPS TO REPRODUCE
1. Open screen sharing dialog in OBS.
2. Select new virtual output.
3. See logs (journalctl -f).

OBSERVED RESULT
Every second:
```
kwin_core: Failed to find a working output layer configuration! Enabled layers:
kwin_core: src QRectF(0,0 1920x1080) -> dst QRect(0,0 1920x1080)
```

EXPECTED RESULT
No errors in logs.

Thanks for the bug report. I'm not able to reproduce this in Plasma built from today's git-master. I also see no other reports of this error.

Is this still happening on your system? If so, please share the output of kinfo

Thanks.

It is already fixed, I think the issue was not linked to the commit.
