is solved with the new driver.

We've switched to the r600g driver, so presumably this issue is no
longer relevant for natty.

Compiz crashes when hitting Alt-Tab - Mesa 7.9 implementation error: bad format
in _mesa_format_to_type_and_comps
Actually, the bug is crashing compiz rather than X.
It sounds like when doing alt-tab, to draw the dialog compiz is passing
in a GL format that mesa doesn't support.
_mesa_format_to_type_and_comps in ./src/mesa/main/formats.c is basically
just a big huge switch statement for every possible texel
The error message is in mesa, so for now I'm guessing it's not a bug in
the DDX driver.
** Package changed: xserver-xorg-video-ati (Ubuntu) = mesa (Ubuntu)

Try this mesa patch, which will make mesa tell you what gl format number
it received. Might be a useful clue.

Compiz crashes when hitting Alt-Tab - Mesa 7.9
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
Chris thinks this is a mesa/r600 issue, and that switching to r600g (the
gallium driver) will resolve it.
Alternately, you could try turning off mipmapping in the switcher
options as a workaround.
