You have been subscribed to a public bug:
when fractional scaling is enabled for example 150%, trying to
fullscreen the video playing in the browser or in the video player,
display suddenly goes black, and then video resolution size is reduced
to 1/4 of the actual screen size, with a still frame from the video as
background and every app opened in the bacground becomes so large that
it goes out of the window. also the mouse cursor stuck on the screen if
auto login is disabled
