The colors seem inverted : I take a screenshot of my blue-colored compiz on ppc,
then I view it inside the same bugged environnement.

As you see, the Ubuntu's logo and Firefox' icon look out well again, respecting
their true colors…

I precise that gnome-compiz-manager has nothing to deal with that bug : I had
got this bug before gnome-compiz-manager was installed…

I use the official Ubuntu Edgy Eft packages :
compiz-core 0.0.13.38-0ubuntu3
compiz-gnome 0.0.13.38-0ubuntu3
compiz-plugins 0.5-0ubuntu3

I'm seeing the same problem on a G3 ibook.

I've the same bug with gentoo on an ibook g4 12". I've used this overlay
http://svn.hboeck.de/xgl-overlay


That are my softwares version:
ibook mambro # emerge -av libdrm mesa xorg-server xf86-video-ati compiz

These are the packages that would be merged, in order:

With mesa 6.5.1 and compiz 20060913 doesn't work yet... is someone working on
this problem? You need other information?

With mesa 6.5.1 xorg-server 1.1.1 and compiz 0.2.0 if I use display Depth 16 bit
(DefaultDepth 16 in the Section "Screen" of the xorg.conf) it works better but
not perfecty yet. 

This is a screenshot
http://img181.imageshack.us/my.php?image=aiglxcompizwj1.png

You can see that some parts of the screen are purple/blue.

There is a patch here :
https://launchpad.net/distros/ubuntu/+source/compiz/+bug/58373 the eigth comment.

As noted in comment #7, this was a bug in AIGLX that I fixed for X.org 7.2.
