Correction: the bug occurs with both twinview and 4-separate-screen X configs. I'm now testing twinview without Xinerama enabled. This could possibly be a Xinerama+Xorg+mouse issue.

I have not experienced the bug with 2 twinview screens and xinerama turned off.

I'm having the same problem with the same graphics card, and 4 monitors.
I've confirmed this bug only occurs when Xinerama is on.

Hi lukehoersten,

Thanks for including the attached files. Could you also include your /var/log/Xorg.0.log?

I have had the same problems. I immediately saved my xsession-errors file off when this happened to me recently. Attaching a copy..

This has also been heavily reported in Bug #296167.
