Well, Aaron Plattner posted about this bug in the ubuntu tracker here: https://bugs.launchpad.net/ubuntu/+s...ne/+bug/605979
, so even if someone doesn't reply to this thread, they do know about it.
Using the Xrender gradients also resulted in some fairly bad speed hits, too. Since the 6 and 7 series don't have hardware gradients, and cairo is still going to be requesting server gradients due to the Xrender version, there will need to be a better-performance software fallback in place. As it is now, cairo's software implementation is much faster than whatever Xrender is falling back on.
