What desktop theme do you use?
Created attachment 138434 [details] Breeze task switcher without blur (In reply to Vlad Zahorodnii from comment #2) > What desktop theme do you use? Breeze global theme. Blur is not missing all the time, the bug occurs sometimes after I change some Plasma settings. I was able to reproduce a few minutes ago by changing global theme and gtk theme (I can't reproduce again doing the same changes though) and not even reboot fixed it. I had to change global theme and switch back to Breeze to get a task switcher with blur again. I'm posting a screenshot showing Breeze task switcher without blur.
Same here, I've tried changing the desktop theme, but the background behind the task switcher is blurred all the time. I have a suspicion that it might be a plasma theme related bug.
