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.

Martin

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.
