[madbiologist (me-again)]

This should be fixed in the newly released mesa 7.7-3ubuntu1 package.

From the changelog:

[ Brice Goglin ]
  * Pull from upstream mesa_7_7_branch up to commit 2f28ca0a.
    + Fix funky colors on radeon/r200/r300.

This is the same commit in the Debian changelog, where it actually mentions gears colours:

+commit 2f28ca0a27cb0c539affb22c487c4bb44b6d54b4
+Date: Wed Jan 27 11:46:26 2010 +1000
+
+ radeon/r200/r300: don't clean non-emitted state.
+
+ So if we don't actually emit an atom to the hw because we don't
+ need it in the current state (e.g. lighting related atoms when
+ lighting is off) then don't mark it as clean, because when
+ lighting gets switched on we won't emit it at all.
+
+ This fixes funky gears colors.

Can you please update to the new package and test?

[Bryce Harrington (bryce)]

Since there's not been a reply we'll go ahead and assume it did indeed fix the issue. If this is wrong feel free to reopen with further clarification.

[Detlef (winspool)]

Yes, rendering in glxgears on ATI R100 is fixed.
Thanks
