SUMMARY STEPS TO REPRODUCE 1. Login to Wayland session 2. Go to Display Configuration 3. Change the display scaling from 100% to 125% OBSERVED RESULT The currently opened System Settings window and also the task manager are blurry. This fixes with logout/login again. EXPECTED RESULT Plasma should not require a logout/login to fix blurry apps, they should not be blurry after the change in the 1st place.
