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.
