### Hit Alt-Tab ###
Mesa 7.9 implementation error: bad format in _mesa_format_to_type_and_comps
Please report at bugzilla.freedesktop.org
compiz: main/mipmap.c:43: bytes_per_pixel: Assertion `b >= 0' failed.
Aborted

Has tried both "Application Switcher" and "Static Application Switcher", nearly the same output after hitting Alt-Tab. Also deleted ~/.config/compiz/ and ~/.gconf/apps/compiz/, with no good.

Your driver is bad. Please reassign this to radeon

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 format, which is used to generate mipmaps. In this case, it is getting to the end of the switch statement, where it hits the default, which is to issue the format error:

      _mesa_problem(NULL, "bad format in _mesa_format_to_type_and_comps");

So, we need to know what format compiz is passing in.

[Bryce Harrington (bryce)]

The error message is in mesa, so for now I'm guessing it's not a bug in the DDX driver.

[Bryce Harrington (bryce)]

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

[Chris Halse Rogers (raof)]

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.

[Bryce Harrington (bryce)]

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.

Another option is to add a quirk for that driver in the detection
plugin and neuter the function which generates mipmaps, although this
is evil and should be a last resort if we cannot fix the driver.

[Omer Akram (om26er)]

is this still an issue in Latest natty?

[Bryce Harrington (bryce)]

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

[Victor Vargas (kamus)]

I will mark this task as closed due to the last comment this behaviour is solved with the new driver.
