This is v2.1.3 year 2007 highest version for Tiger and a Universal
Binary. Quartz Debug is a tool that began in 2001 for troubleshooting
a GPU assisted video generator, that being "Quartz Extreme" was
Apple's name for this GPU assisted compositing technology.
Quartz Debug comes supplied with the Xcode Developer Tools, this
version (2.1.3) the highest for Tiger was extracted using Pacifist
from the Xcode 2.5 Packages/Packages/TigerPerformanceTools.pkg for
convenience and avoiding the performance drains associated with the
full Dev install.
One thing, you can use this app to Disable Beam Sync in Tiger all
10.4.n when you launch Quartz Debug, then choose its option to disable
Beam Sync, and then FORCE Quit instead of properly quit Quartz Debug.
After that, it seems disabling the Beam Sync setting (if that is what
works for you) will need to be repeated on every restart of Tiger.
