Unfourtunately I am not a driver developer, however I can play a bit arround
and see how things change.

> There have been a few reports of things not being drawn on NV1x,
Interesting you mention missing things, because when I go with grayscale
antialising I can see missing text on the desktop icons. I didn't mention it,
because I guess it is really hard to reproduce.

However, shouldn't this just affect the glyphs rendered? The blending mode of
the icons doesn't change, so it seems some state is garbled after the glyphs
were rendered, leading to those misrendered icons.
