Comment 120 for bug 745608

Just to be thorough, I'll report that updating to server version and Intel driver version 2.15.901 does not appear have any effect at all on the problem.

However, according to other information on this ticket I'd expect to see this problem on Fedora 14 (with xorg-x11-drv-intel-2.12.0-6.fc14.1.x86_64 and kernel- but everything is completely fine there. That F14 kernel does, however, carry a few i915-related patches; I'm not able to tell if they have any bearing on the issue.

Regardless, this looks like an annoyingly complex issue.
