Could you provide a screenshot?
I recently had an issue with certain programs causing text to display oddly. Had something to do with the latest AMD drivers - have you updated those lately?
If it's a Cleartype issue, a screenshot might not really work as expected. Cleartype does its thing by manipulating the fact that each pixel on your screen actually consists of 4 lights of different colors, in 4 different locations (essentially quadrupling the amount of pixels on the screen available for text). I'm not sure, but it might not translate well to a different screen.
Right... the issue I had was not with cleartype, and did show up via screenshots, so that's why I was asking for one - just curious if it was the same problem I was experiencing (though I didn't find a solution other than to wipe and reinstall)
