Thanks, I appreciate the informative response. The word 'tearing' escaped me while I was posting. You make a good argument for leaving Beam Sync enabled. I do remember playing full screen videos in 10.3 and witnessing some tearing. I don't however remember window tearing being that drastic though. At least nothing compared to the tearing I used to see in X-windows under Linux, or after I turned off Beam Sync as described in the hint. Also I thought Double Buffering helped prevent window tearing?.
Found the defaults to change: use this console cmd:sudo defaults write /Library/Preferences/com.apple.windowserver Compositor -dict deferredUpdates 0You can verify this by opening /Library/Preferences/com.apple.windowserver in Property List Editor and expand 'Compositor'Open Quartz Debug and reveal the Beamsync tools. Change the setting.Reopen /Library/Preferences/com.apple.windowserver and expand Compositor to see the new setting.0 = disable beamsync1 = Auto beamsync2 = force beamsyncOf course, YMMV.Enjoy!.
