When watching YouTube video in full screen I get a really strange effect. It happens if I do not move the mouse for 3 seconds and the interface gets hidden. When I move the mouse, the video plays fine again.

Here is a screen capture which shows the "effect": https://www.youtube.com/watch?v=DPkaDtvYVPs

It is worth to mention that I have "youtube freeze" issue ticket which haunts me for along time ago: https://bugs.webkit.org/show_bug.cgi?id=172762
