SUMMARY
When I put any video player in the second screen, maximize the window, and then i click on "Fullscreen" (on the video player (ex. Youtube, Twitch, MpvPlayer, ecc)), the screen goes to black, but the video is running and i can click the screen for leave fullscreen mode and all re-turn to normal. If i click "Fullscreen" in a window NOT maximized, the video goes fullscreen without problem.

2. Maximize this window
3. Click "Fullscreen" or another button for watch the video in fullscreen

OBSERVED RESULT
Black Screen and the video still reproduce
