I am having a issue when I watch any kind of flash player video (Twitch/youtube/other stuff) on mozilla firefox. https://i.imgur.com/P9HFXSk.jpg As you can see on the picture there are stripes or color differences that look like stripes in the picture. I only have this problem with mozilla video viewing and not when I use google chrome to watch youtube etc or watch through a media player like VLC. The stripes disappear if i pause the video otherwise they are always there during the video. I have tried turning on and off hardware acceleration.
