Anyone know what's causing this?

Having fucked up the picture upload is definitively one of the primary causes.

fixed.

That would be the shaders fucking up.
What's your card make/model?

I've never seen that one before. I suspect a driver problem.

Yup, I say driver problem too. Report your GFX card's make and model, and driver version. And also OS used.

Change texture format to rgba8 and turn off mipmapping. It's corrupting the mipmap somehow and your driver doesn't like it.

That's a cool-ass effect though.

Neither of them sounds very promising, although the 4500 is supposed to have proper unified shaders by now and "real" 3D acceleration. Guess it isn't as full-featured as one from Ati or Nvidia though.
