SUMMARY

Hi there :)

When I manually adjust the brightness level, the slider of the Brightness and Colors widget resets to 30% 
It does not reset the actual brightness, mind you. 

Still, whenever that value is read by Plasma, it obviously jump to that level:

Let's say I set the brightness level to 5%, and set "Turn off screen" for "When laptop lid is closed" 
Closing and opening the laptop lid brings the brightness up to 30% now. 

I assume this was due to the upgrade to Plasma 6.0.5 or Qt 6.7.1

I now realize, the OSD has no effect on the widget. Changing my display brightness via keyboard combinations shows the change on the OSD and actually changes it. Here is my log, journalctl -b: https://dpaste.org/rvht4

So only the slider in the widget is broken, and the keyboard shortcuts work as expected?

Well, yes and no. I also experienced, that the brightness was always reset to the level, that the widget was set. But with a recent update, but seems to be resolved. Closing for now, will open it again, if it comes back. Thanks a lot
