During configuration of a new install with Openbox as the “main” desktop I installed Gzdoom and played some scenarios (fullscreen). When I turn off the game I get 1/4 (upper left corner) of the workspace/desktop back! The rest i black! It’s not a big problem because just a logout and in again restores the desktop.
I find it hard to search for these kind of problems therefore I wonder if anybody recognize this?
Very thankful for a hint!
