Confirming the patch indeed fixes all cairo symptoms (patch itself
doesn't apply cleanly, but consists of three lines total, so it's an
easy edit). All performance and button rendering issues are fixed (which
is pretty scary, by the way).

Also per the following thread, the regression seems to target
specifically 256. and 260. series of nvidia drivers (well, any nvidia
user with a modern graphics card anyway):

As the patch is already included (or being included) in most major linux
distributions, I'd assume it doesn't break stuff for non-nvidia users,
so we should probably include it too. Refs:
