I have 2011 15 MBP 2.2, and I use chrome as my primary browser for various reasons. I also use GFXcardstatus to monitor which graphics card is being utilized since I want to maximize battery life. Chrome always bumps to the ATI card but I can lock it to integrated only. But when I do that I always have issues playing web based video. Some videos will work until I full screen and ten it goes just black. Other times on YouTube the sounds plays, but where the video should be playing I actually see my background wallpaper. Is this everyone's experience? And can someone explain to me why this is happening?
