Description Patrick Silva 2022-01-14 18:02:07 UTC 
STEPS TO REPRODUCE
1. open Display Configuration KCM
2. use the slider to change display scale from 100% to 125%
3. click on 'Apply' button (dialog to keep/revert the change shows up, click on 'Keep' button)
4. use the slider to change display scale from 125% to 100%
5. click on 'Apply' button (display scale 100% is applied to my screen but no dialog shows up this time)

OBSERVED RESULT
display scale is reverted to 125% 15 seconds after the last step and the KCM displays "Display configuration reverted." inline message.

EXPECTED RESULT
changes done in Display Configuration KCM should always be correctly applied
