Solution!
I was about to post here saying I had the exact same problem (the "blueish" screen when Google Chrome or Photo Booth were running), but I just made the software update (just now, October 15, OS X version 10.8.2) and everything is just great.
It was very awkward, however. Yesterday my MacBook Pro was working just fine and I decided to turn it off. Today when I turned it back on it's screen got "blueish" the second Google Chrome started running. I desperately googled it until i found this thread, but then I updated it and it's just fine.
Hope I helped.
