Hey everyone,
Call this a coincidence or fluke, I had the same issue as OP; screen acting all weird after waking from sleep. This is on my MBPR of 2 months. This is the second machine they exchanged for me also having the same problem come back. Always seem to reel its ugly head when I start to mess with screen saver or Energy saving settings.
Brought it in to the Genius bar after it started misbehaving last week after a presentation I gave using Numbers.
Findings
They ran a basic hardware test on it then advised they need to check my machine in for a day or two to do a "graphic" stress test. Not sure what it entails but they found nothing wrong and did a OS reinstall as a precautionary measure. When I picked it up, a different Genius Rep told me this is most definitely a software glitch. Machines ranging from his own MacMini to some customers' iMacs have been having this problem. He assured me that Apple is coming up with a patch soon. How soon? He said he doesnt know and that Apple Engineers are advising a work-around...that is in Security settings, do not check the "Log in required after sleep" option. Meaning, no log in screen upon wake from sleep or screensaver. I found that interesting since this seems like the only place that my screen misbehaves; At login screen.
Then lo and behold, one night after I get my MBP back on Monday, Apple released an SMC and OS update...can't remember the exact verbage but resolving the screen resolution and video glitch is one of the problems the update aims to resolve. Ran the update (after a painful experience to find out I cannot restore from my Time Machine the way it was intended after my HD wipe) and <touch wood>, haven't had the display glitch from sleep yet!
Curious, how's the patch working for everyone else?
