Ever since I upgraded to Waldorf a couple months back I've noticed a weird artefacty static in Youtube videos that wasn't present before. It doesn't show up on Vimeo or Dailymotion or literally any other video i see online, but only in Youtube videos (even the preroll advertisements don't have the static!) It happens in both chromium and goog-chrome-stable, but not in iceweasel.
I haven't a clue where to begin so I throw this to you cunning folk.
Here's an animated gif of what it looks like, just picture the static moving 3 times as fast:

i had this problem using chrome but not when using chromium. It's a problem with the player chrome uses for videos in html 5 enabled websites. I work around i guess would be to watch youtube via flash rather than html5 video or give chromium a try.
