Hi Damien, Thanks for your suggestion. Setting 'Option "AIGLX" "off"' in the ServerFlags section of your /etc/X11/xorg.conf fixed the problem. Disabling DRI also fixes the problem. Unfortunately both solutions make rendering SIGNIFICANTLY slower. Note that I am also seeing this problem with my ATI Technologies, Inc. RV280 [Radeon 9200 PRO] card using the "radeon" driver.
If anyone knows of any other fix for the problem that doesn't have slower rendering as a side effect, or has any more info on the nature of this problem, please let me know.
