What I see after enabling Desktop Effects.

Description of problem:
I have to set

    Option "MigrationHeuristic" "Greedy"

in xorg.conf (attached) in order to get decent EXA performance out of the intel driver in plain old X. Enabling Desktop Effects leads to a mostly corrupted screen.

Version-Release number of selected component (if applicable):
xorg-x11-drv-i810-2.5.0-3.fc10.x86_64
kernel-2.6.27.7-132.fc10.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. Set MigrationHeuristic to Greedy.
2. Start Desktop Effects.
  
Actual results:
Large parts of the screen garbled or blank.

Expected results:
Desktop bling to die for.

Additional info:
xorg.conf, Xorg.0.log from a typical session, and screenshots attached.
