Has anyone noticed any excessive color banding on the Voodoos at 16bpp
(relative to other cards)? I noticed it first in evas_test_old, the test
application for Raster's Evas library. This is with DRI CVS drivers from
at most two days ago and the Glide3 library from the same day.
Further, it seems that the 810 has color banding issues as well as being
unable to render several things in the test. In particular, these are the
text covered primitives - it appears as if the alpha is being ignored
(set to 255) for non-zero and non-255 alpha. There is also significant
color banding with the 810. Drivers are from DRI CVS as of two days ago
I didn't notice it in Quake for either card, but it's not so easy to spot
color banding in Quake as the textures are fairly detailed.
I originally thought it might be an Evas oddity, but the other cards I've
tried are more or less correct (G400, Geforce2s, ATI Rage128).
