Tested on: WebKit browser WebKit-SVN-r131444 Google Chrome Version 23.0.1271.64 m (Seems to use webkit 537.11) Safari 5.1.7 Platform: Windows 8 Professional, 64 bit Linux Mint 11 If you hover over the navigational links at the top (home, android, websites, ...) the HTML5 video below starts to flicker. Try to make the browser-window full screen so that you see both of them at once. Also tested on FF, Opera and IE - it works fine there. Variant: sometimes the HTML5 video's "poster" image just drifts a bit to the left (1px - 3px), instead of completely becoming white. Also note, that the navigation links are shifting to left after the 10px-down translation.
Seeing this (when video is not playing) with Safari 6.0.2 on OS X 10.8.2.
