Dear Maintainer,

since upgrading Qt to 6.11.2 in sid, powerdevil actions after inactivity
like screen dimming, turning off the screen or suspending do not happen
any more. Journalctl shows the following error message:

org_kde_powerdevil[]: qt.nativeinterface: Native interface revision mismatch (requested 1 / available 2) for interface QWaylandApplication

Please let me know if I can provide any additional information.

Regards,
Sönke

This is a known bug, but the actual culprit is libkf6idletime6 which had
to be rebuilt against Qt 6.11 as well.

libkf6idletime6  6.30.0-2 fixes the issue and has been available for a
while in sid, not sure why you don't have it installed yet.
Please upgrade libkf6idletime6 and see whether that fixes your issues.
Feel free to re-open this bug if it doesn't.
