Actually, your description of the problem is probably better than mine.
I couldn't think of any word other than 'blurry' to describe it, but I
think what you said is a bit more detailed and probably more accurate.

Everything that I've read about this (there really isn't that much about
it AFAICT) suggests it's an nvidia driver issue.  I don't have any way
to prove it one way or the other though.
