Weird pixel problem (not dead and not stuck)

[gte204i]

When I received my T42 a few weeks ago, I didn't have any bad pixels. But yesterday, I start to notice some weird behavior out of one pixel. Here's the deal:

Background color - Weird pixel color

Blue - Black
Black - Blue
White - White
Red - Red
Green - Green

It's like the blue pixel intensity is reversed or something. Anyways, I haven't updated the drivers, so I will try that. I don't think it could be an LCD problem. It seems like the video card or drivers. Any ideas?
