Interesting. A few random troubleshooting ideas. Try moving aside your
.drirc. Run a video player with its --debug option and look through its
output for any noteworthy error messages. I notice a fb tiling warning
in your Xorg.0.log. Do a 'tail -f /var/log/Xorg.0.log' in a console
window and then reproduce the issue and see if any messages get printed
in the log.
I assume by the title that you also tested with compiz running and found
it did not happen in that case? If so, you could also try comparing
dmesg, Xorg.0.log, etc. for the two cases and look for differences. (my
guess would be vblank syncing is set differently.)
