  • A quick test to check if driver/graphic adapter issue or Software/Desktop one. Go Settings > Appearance > Behavior > Enable workspaces. Then press Super/Win+s. See if you have this square over all work spaces or it holds same position in the monitor? Take a screen shot and add it to the question.

    Ok, I was simply stupid, overlay was caused by gnome-screenshot (selected only part of the screen and kept the window in background)

Ok, it was my fault.

The overlay was caused by gnome-screenshot still running in background after a screencap was made.

Problem is solved closing all istances of gnome-screenshot
