Video goes to greenscreen when in fullscreen

  • Hi everyone! I am new to these forums.

    I have recently installed Opera for the first time. When I try to watch an online video in fullscreen mode, the video goes to a greenscreen with the video in the top left corner and the video stops playing. Here is a screenshot:

    I have tried several websites and this always occurs. I have got adblocker turned on but I have got data savings turned off. I have tried turning these on and off and have tried using previous versions of the browser but still have the problem.

    I am using a Sunvell Q Android TV Box:
