OS X Lion graphic glitch

I don't know if this issue is specific to Lion or if it's just my iMac, but ever since I purchased my new iMac a couple weeks ago I've been seeing these really weird 8-bit like glitches occuring everywhere, tainting the appearance of the menu bar and dashboard. Here are a couple screencaps of it:

Anyone else having this issue? It doesn't appear to be hindering the performance of the iMac but it's a real eyesore which sometimes obscures the names of folders. I'm using the latest iMac 27" (mid-2011) 3.4 i7, AMD Radeon HD 6970M 2GB GDDR5, 16GB RAM, 120GB SSD, 1TB HDD.

I have the same problem as well. Getting worse. Please note the unreadable menu, strange blocks on the lower left of desktop, and the banding/flickering that's happening during movie playback on iTunes (all latest version software, Lion, OS, iTunes, etc.). running on a 2011 i7 3.4 ghz iMac27 Radeon HD 6970M. May take it into the apple store here in nyc for evaluation/repair.
