Comment 0 for bug 596192

I have a fully updated Lucid-AMD-64 installation with an upgraded Compiz (0.8.6-0ubuntu1).
I also use Emerald (0.7.2-0ubuntu4) decorator for compiz.
Furthermore, I have upgraded my system with all the lucid packages of the PPA Xorg-Edgers-Crack-Pushers,
including the new kernel (2.6.35-4.5), xserver (1.8.1.901+git20100613) and nvidia-current (256.29-0ubuntu1).
Motherboard: Gigabyte GA-MA790XT-UP4
Graphics card: NVidia GTX285

After upgrading the new libcairo2 (1.9.8-0ubuntu0sarvatt~lucid) I noticed some serious rendering issues.
All special effects fails to render correctly, where there should appear highlighting or fading color blends:

1. Emeralds (vrunner 0.2) frame engine blends in the titlebar (especially middle blend) fails to render.
Actually a white blend does not render at all, the whole area concerned turns totally white with no blend at all.

2. Emeralds frame/shadows in gnome panel or in application windows do not render at all.
They disappear.

3. I have also noticed, using synaptic for instance, pressing the reload button, the loading bar fails to show blending colors.
The upper area of the bar is completely white.

The lucid libcairo2 (1.8.10-2ubuntu1) and maverick libcairo2 (1.8.10-4ubuntu1) do work OK.
So downgrading to one of those works.
