Nouveau - Apr 2012 - rendering problems with latest ddx driver (nv50)

Do you get rendering errors also when using a nv50 class gpu? I seem
to get them in firefox.

I also noticed a huge amount of failures when running rendercheck -t
gradients, which i find odd, because they are not supposed to be
accelerated.

Hi,

By any chance, are you using cairo 1.12? If so, try downgrading to cairo 
1.10.

Hmm, I haven't noticed anything on my NVA8 laptop.

I think either pixman or the rendercheck test is broken.  It doesn't
pass with software rendering, or the Intel driver's accelerated version.

The detected/expected colours are very close when I looked at this, so
it may just be a question of precision.
