Hey Outkast. I actually just sent my macbookproret back to apple (with applecare) for this exact reason.
Numerous people on youtube are posting similar problems (my flickering happened less frequently).

I also noticed (and I think this may be related) in safe mode that everything was really glitchy and slow to open. For instance when I opened launchpad everything opened really glitchy and looked like the blinds of a window when open.
Additionally I had some ghosting when visiting certain webpage. Particularly brightly colored web pages.
You should try running safe mode and see if you notice anything funky in there too. I'm thinking that something is screwed up with the logic board and display... kinda hoping that they just replace the machine.
