Created attachment 142654 [details] Blurry window example SUMMARY When resuming from sleep out of focus windows are all blurry and unreadable. I have attached a screenshot to show the issue, the image is taken with the immediate option in the screenshot program, otherwise the windows are in focus, i don't know if kwin changes behavior if it detects that a screenshot is being taken. The lower left of the terminal shows what the window should look like when it's in focus, as it appears to be in the middle of rendering the effect on that window. The problem doesn't exist on login, only after suspending/resuming. STEPS TO REPRODUCE 1. Suspend system 2. Resume system OBSERVED RESULT On resume windows fade in and out of focus, the active window will phase back into focus as the background windows blur so much that they are unreadable, the blurring doesn't look intentional, the text is being pixelated so the effect is not a smooth blurring.
