In response to comment 10, I have a three head machine (2 on an mga dual head card and 1 on a usbvga adaptor using the sis chipset) and can confirm that the problem does occur when switching between the two mga heads.

I have not been able to confirm it, but a co-worker with a similar setup says he had the problem happen once without actually switching between heads. We both have the symptom occur several times a day, but so far the quick fix of moving a window from head to head fixes the issue.

The problem does seem to be limited to xinerama as I have another setup with an ATI card using randr in xorg.conf but otherwise identical software (all machines mentioned are running from an LTSP server with the same image, just different xorg.confs) that does not have the problem.
