Description Alexander Potashev 2020-04-30 21:31:27 UTC 
SUMMARY
Cannot revert screen resolution to currently selected in KCM if resolution was changed by another app while Screen KCM was open.

STEPS TO REPRODUCE
1. Open kcm_kscreen. Notice current screen resolution (1920x1080 in my case.)
2. Use another app to change screen resolution, e.g. run StarCraft 2 in Wine that would request a different resolution (1280x720.)
3. Click Apply in the KCM.

OBSERVED RESULT
It won't work because Apply button in KCM is still grayed out.

EXPECTED RESULT
Either Apply should work to revert screen resolution back to 1920x1080, or there should be another way to do it (besides Apply).
