Ok I've switched to dark theme of Plasma repeating the procedure. PLASMA has problems. I noted that sometimes opening the start menu some graphical issue was visible, but now I can state that there are graphical problems about the desktop environment. It is possible to see this issue in the attachment: the visible dark squares are the start menu affected by glitches.
