Comment 4 for bug 219587

> I think ATI (fglrx) is one of those. I will test locally (as I used to have that issue).

to my knowledge its every driver that doesn't ship its own Xaa implementation (e.g. vanilla X xaa) in combination with offscreen pixmaps.

The uncertainty of cairo devs at the time of that announcement was due to the fact that fedora disabled offscreen pixmaps for some time now and thus, there was confusion, because the same version that didn't work for ubuntu worked over there.

However, we don't know 100% and should get proper testing on this in -updates to be sure that the initial mozilla rendering bug (and X _crashes_ in some cases) doesn't reappear for some users if we drop this patch.
