I don't know if this is a Chrome bug or a YouTube bug...but every YT video I start shows me a black canvas instead of video, while the sounds plays normally.
The only way I managed to figure out how to get the picture back is to click on another tab, go back to YouTube tab and scroll down a bit. When I do that, the video appears.
It doesn't happen in Vimeo, so I presume this is not a Flash related issue?
