Ever since updating my 15" rMBP to 10.8.3, and installing the SMC update, I've been getting a very frustrating restart glitch, which occurs directly after exiting a full-screen game (specifically a skiing game "Shredsauce"). This has never happened before, and I can only assume it is do to the latest update. It doesn't happen every time, but it happens often enough to be a piss-off. Has anybody else noticed this? Or had something similar happen after the latest updates?
