I just noticed my screen is starting to do the same thing! It is a 20" Aluminum iMac, bought it back in November. I do not smoke anywhere near my computer, I live in WI so it has been cold and dry, and I also have electric heat which keeps the air super dry. Time to get a hold of Apple, it is very nice living only 15 minutes from TWO Apple stores, lol.
Here is a picture of my problem, I turned it towards my window so it would show up on camera. My iMac is never hit by direct sunlight.
