I'm running Ubuntu 18.04. At random, my screen windows turn black. However, app bar and side bar stay visible. Doing a "ctrl-tab" shows running apps, I can switch apps, but all app windows remain black (see screenshots). They stay black and I can't seem to recover from it other than logging-out and then back in which is super annoying since I lose the work that's on the desktop and I lose a lot of productivity. The "black outs" only happen when I either do a mouse click or switch windows. Black-outs never happen self-spontaneously.
