rendering problems with latest ddx driver (nv50)

rendering problems with latest ddx driver (nv50)

[Maarten Maathuis]

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.

No, i'm using cairo 1.10.2. Also rendercheck isn't affected by cairo.
The last driver upgrade included at least the migration to the new
libdrm and everything that came after it. That's when the rendering
corruption started.

Right, I was under the asumption that both issues were un-related.

I guess you are using the latest ddx which does accelerate solid pictures.
Have you tried resetting to this commit ?

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.
