From e.g.: Amazon Prime Video. Actual results: When I html 5 videos on the secondary monitor switch to full screen remains a window border exists. On the primary monitor, the window border is not. Secondary monitor: 1680x1050 & primary Monitor: 1280x800. Screenshot in the attachment. Expected results: I would like the secondary monitor again without a window border. That was with the versions 56>.
Hi Alexander, Thanks for reporting this bug. Just want to double confirm does that border only shows when video playback is in full screen? Can you see that border in non-video-playback case?

Hi Blake Wu, I've tested a bit: in normal surf is the border there, should be so. In full screen mode (F11) he is there too, I think that's wrong. And with the flashplayer, the border is there too.
