Description Lyubomir 2021-09-14 16:35:47 UTC 
SUMMARY
(in disagreement with System Settings value)

STEPS TO REPRODUCE
1. Login to Wayland session
2. Change scale to 125%
3. Logout
4. Login to X11 session
5. Logout
6. Login to Wayland session

OBSERVED RESULT
Notice how the System Settings/Display Configuration shows 125%, but in reality the display is not scaled at 125% but at 100%. There is a disagreement between the shown value and the effective value - everything is small at 100%.

EXPECTED RESULT
Logging into a Wayland session after a X11 session was used before should result not only in System Settings showing 125% value, but also in KWin respecting that value effectively.
