I can reproduce this frequently just by switching between images in GQView that have different widths: the sides of the wider image are often left behind next to the narrower image (see attached screenshot. The nvidia driver put the black bars in on the side).
This doesn't happen with the nvidia 173.14.12 driver, only with the 177.70 driver. I'm running 2.6.27-3 amd64 and GQView 2.0.4-3.
