Ton,

The problem is obvious in the two images: my card don't draw solid 
colors but uses dithering. That why color is not constant on the faces. 
I tested with the gimp and actually colors are close to what they should 
be, but there is a repeated dithering pattern that implies that the 
color is never exactly the one it should be.
I don't know if there are other cards doing this, but none of them will 
ever work correctly with blender z-buffer  clipped selection modes or 
with UVface-mode.

Do you see any solution?
Again, what about the algorithm I described in my previous e-mail?

Thanks for you help,
Stéphane
