Comment 39 for bug 314928

Looks like there is more than enough information here to send this to the intel driver developers.

I strongly recommend that someone who experiences this bug and understands the issues opens a high quality bug report at http://bugs.freedesktop.org/ (file against xorg and set component field to Driver/intel). After doing so, connect this bug report to the upstream bug report by clicking the "Also affects project" link at the top of this page.
