Description David Kredba 2022-12-29 18:37:04 UTC

SUMMARY
Screen scale seems to go to 100 % from 150 % after some session uptime and an icon on the Desktop is clicked. In my case it happens when I try to open a txt file stored there. Opening is set to double-click event, the re-scaling happens after the first click is made. The wallpaper downsizes too at the same moment. Can be 'fixed' by log-of and log-on or by setting Scale to 100 % and back to 150 %. The re-scaling affects played video (mpv) window too.


STEPS TO REPRODUCE
1. Use two monitor setup. Left 4K, a Scale set to 150 %, right 1K, a Scale set to 100 %, KWayland session.
2. Use the session for some time
3. Double-click on an icon on the Desktop

We've not had any other reports of this and it sounds very unusual

Please attach `kscreen-console bug` before and after this happens.
