Flash videos go haywire in fullscreen mode in Google Chrome 20

http://askubuntu.com – Whenever I go fullscreen on a youtube video, there is a moment of static, then the controls continuously jump all over the screen, and it seems like the player is trying to center the video between both monitors (I have a two monitor system). Never had any problems watching full screen flash videos with my dual monitor setup (same hardware) in 11.10 or 10.04. This problem only began after upgrading to 12.04. Here is a screenshot (showing both monitors, fullscreen video on the left): (not enough reputation to embed... lame) - http://i.imgur.com/Euwzu.png No other graphics problems on any ot (HowTos)
