Isn't tearing exactly what Beam Sync prevents?
Authored by: slacks on Jul 06, '05 06:18:31PM

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?

Yes, I second: beamsync prevents tearing. Double buffering only prevents tearing if the buffer is copied to the screen in sync with the refresh rate.

Did anyone notice that "Quartz Debug" has an menu item to enable/disable "beam sync". So why use the command line tool?

Using Quartz Debug was part of the original hint. Downside was you had to force quit the program in order for the settings to stick, otherwise they would revert.
