SUMMARY This is probably not a KScreen bug, but it affects all KDE applications so I am not sure where else to report it. I hope the devs know the right product/component for this. :) I also probably used the wrong keywords when searching since I assume this has already been reported? STEPS TO REPRODUCE 1. Have some KDE applications running 2. Change screen scaling to a different value OBSERVED RESULT The applications adjust their scaling in a way that is very blury, it's hard to even properly read text. After logging out and back in, everything is crisp. EXPECTED RESULT Things should scale properly and crisply immediately. Having to restart all my applications is a big disruption of the work I am trying to get done and should not be necessary.

It's actually a Qt bug that's already fixed in Qt 6. Unfortunately the change was not backportable to our Qt 5 patch collection.
