Since I downloaded docker on my computer I get this strange behavior from chrome when I use it in another workspace. It's not updating the screen properly somehow and it's hard to explain so look it in the gif here. I have google-chrome-stable (86.0.4240.75-1) firefox seems fine. My ubuntu is 16.04. Also it's only if it's fullscreen.
UPDATE: updating my Ubuntu to 18.04 solved the problem. You can also downgrade your version of chrome to a working one as suggested bellow in the answers
