I'm looking into a similar problem with r600, although for me mesa simply causes compiz to segfault.
For the bug I'm looking at, there are two work-arounds:
1) Disable mipmapping in the switcher preferences, or
2) Enable r600g by adding the ForceGallium option to xorg.conf
They're just work-arounds, but it'd be nice to know if they work around your bug, too.
