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. -- Compiz crashes when hitting Alt-Tab - Mesa 7.9 implementation error: bad format in _mesa_format_to_type_and_comps https://bugs.launchpad.net/bugs/682327 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
