I have some issue with my desktop. When I run apps, and switch to desktop, it show blur activities of my apps on 4 corners. I used KDE and my screen resolution is 2560x1440. It’s kind of weird. Details on my picture.
That’s normal behavior from “Show Desktop” button/key shortcut. You can use the alternative of “Minimize all windows” to avoid it.
Thanks for your answer, but I’m using KDE, no option “Minimize all windows”, just “Minimize window” and “Show Desktop”.
Thanks for your reply. I found the solution, just install Widget Minimize Windows and assign shortcut to it. Minimize window option just minimize one-by-one app, not what I want.
