Description of problem:
ImageMagick's is completely unresponsive and shows empty application
windows when EXA acceleration is active for an ATI Radeon X800 card.

xorg-x11-drv-ati-6.7.195-5.fc9

How reproducible:
Always.

Steps to Reproduce:
1. Open some image file with ImageMagick's 'display' command.
2. Click point in window to make toolbar visible.
  
Actual results:
Toolbar appears but is empty. Random clicks inside the toolbar let
submenus appear but the application seems to be saturated. It's very
slow, unresponsive, and impossible to use.

Expected results:
ImageMagick operates normally.

Additional info:
- selecting XAA acceleration allows to restore normal operation.
- this is with plain metacity - no compiz.
- no other application shows similar problems when EXA is enabled.
