Comment 128 for bug 745608

I can confirm that the issue is still occurring (and is reproducible within 30 seconds using the original steps) in the Fedora 17 and Ubuntu 12.04 betas (which are using v2.18 and v2.17 of the intel driver). The DebugWait option still resolves the problem too. None of the other options (DebugFlushBatches or DebugFlushCaches true, Tiling false) resolve the issue.

Using xorg-edgers ( https://launchpad.net/~xorg-edgers/+archive/ppa ) and sarvatt's intel-sna branch ( https://launchpad.net/~sarvatt/+archive/intel-sna ) also resolves the issue.
