Comment 60 for bug 254468

Just as a datapoint to the Xorg maintainers reading this:

Since the patch has been applied to Ubuntu's Xorg, compositing has slowed down for me to a degree that I'm now running without it.

For example, it takes well beyond one second to get the yakuake window up with compositing on, while before the Ubuntu Xorg packages were updated, it would be almost instantaneously. It's absolutely swift with compositing off.

I'd much rather have the momentary garbage on the screen, that was only a visual distraction but didn't actually render the system less usable.

Hardware is ATI x1300, symptoms happen with the last couple of fglrx drivers and the free radeon driver in Intrepid.
