Comment 9 for bug 647437

@madmed: so this card/driver combination seems to have issues with mutter anyway, but here are a few elements that can help to investigate the problem:

1. Can you provide some glxgears performance numbers? under both fglrx and the open source radeon driver; to see if something is obviously wrong in the configuration

2. Can you post some examples of the corrupted display you're getting with the radeon driver; does it looks like what is reported on https://bugs.launchpad.net/unity/+bug/641674, or http://imagebin.org/117525?

3. You're saying that Gnome Shell doesn't work as well: do you have a bug report for that? is it the same symptoms or is there something more specific like crashers or errors on specific circumstances?
