Weird screen while playing game

[korbearus10]

I was playing a casual game of HoN (Heroes of Newerth) on the rMBP and I was getting this weird white, choppy screen throughout the whole game. I completely exited out of the game and tried getting in the game again, and the same thing happened. The pic:

I didn't have this problem the last 10 days, but it just started today. Is this a hardware problem, or a software problem?

windows or OSX, did you try restarting the machine and trying again?

OSX and I just restarted and tried again. Same thing happened. It wasn't like this even 12 hours ago.

Are you playing on native res? (if not, what resolution?) This might get fixed with Mountain Lion. If not, its a probable gpu not being stable. The GPU in the RMBP is way overclocked compared to same cards in other computers.
