Mouse/Hand cursor won't go away in fullscreen on youtube videos (HTML5)

Hi there,

Sorry if this has been covered yet but I really couldn't find anything. Here's my issue: whenever I'm in watching a video on youtube using Safari 6 and I hit fullscreen, the mouse won't go away which is really annoying. I should mention that, by default, Youtube lanches HTML5 on Safari, whilste on Google Chrome it still uses Flash (we're talking about the EXACT same video!). Oddly enough, I don't experince this issue on Chrome.

Any guesses, tips or resolutions out there ?

Thanks a bunch !

Ric.
