This is a known bug in the Mesa version shipped with Red Hat. We haven't
found a workaround yet.

By the way: I think it is time that this gets mentitoned in the
documentation.

Yes. I had a Voodoo 3 card myself some time ago and I noticed the same
issue with Glide 3 / DRI.

It does not harm at all, but if you want to turn it off, do the following:

export SSTH3_RGAMMA=1
export SSTH3_GGAMMA=1
export SSTH3_BGAMMA=1

A good place might be ~/.profile.

Please grab the RPM package that contains the fix here:

ftp://ftp.redhat.com/pub/redhat/linux/rawhide/i386/RedHat/RPMS/Mesa-3.4.2-9.i386.rpm

There is no need to install Mesa from sources. That's not a good idea if
you
use DRI unless you know excactly what you are doing. As a general rule,
always use your distributions packages wherever possible unless you know
what you are doing :).

Find out yourself. If you ask questions that are mainly about taste, habit
and ideology like this one you usually get very different and maybe useless
(depends on where you ask) answers :).
