Before and after - fixed choppy Spaces in Snow Leopard

[yCherkashin]

What you did, is make everything (individual windows) animate separately, instead of trying to hit a frame together. Some things will animate faster, some slower, and the ones animating slower won't hold up the overall animation.

On my pre-nVidia Mac Mini connected to a 24'' screen both ways it will start lagging when more windows are open than there is VRAM to hold them. With beam sync it just looks choppy, without beam sync it look weird, because the animations race to the finish line.

Quartz debug trick does not work in Snow Leopard (once you quit quartz debug things are back to being choppy).

However, the following command

sudo defaults write /Library/Preferences/com.apple­.windowserver Compositor -dict deferredUpdates 0

will turn off beam sync permanently (you need to reboot for this to take effect). The default value is 1 if you ever want to put it back.

Note however, that you may experience video tearing issues instead, or jittery dock magnification with this.
