I installed Arch linux and it came with kde plasma 6 but the thing that i noticed that some icons goes blurrish and pixalated and they turn sharp as soon as i hover over them but when i installed games and played them and when i closed them in fullscreen. my whole desktop turns pixalated and blurry. here is a screenshot its not that severe as when i close the fullscreen application. i tried to change focus settings but it didnt helped. i also tried turning off all windows and desktop effects which also didnt helped
i have this problem too, i think it might be a problem with kde package.

but my whole desktop become blurry mostly after closing fullscreen application
If it’s not just icons, then it’s probably not that issue.
Are you on Wayland or X11, and what’s your screen’s native resolution, current resolution, and scale factor?
Just to offer something here; I was having similar issues and realized that post upgrade from Plasma 5 fractional scaling became turned on in Plasma 6 and at 1.25x (maybe because I am on a laptop?).
After turning it off (setting back to 1.00) it resolved the desktop blurriness for me.
I’m curious if something could be going on with some kind of preferred scaling setting that is getting reapplied in certain scenarios? For instance I still have this issue with SDDM, which seemed to prefer the larger scaling compared to my Plasma setting.
edit: For reference, this is on a Fedora KDE install, and applying Plasma settings (post DPI update) to SDDM fixed that issue too, so that’s part of my thinking there at least
How would a kde lib that’s part of the framework be debugged?
I want to learn.
