ps wuax | grep [x]compmgr -> nothing. If I run the command myself, bug
happens anyway. What is more, it happens when running xcompmgr -c and
things are worse, the shadow is left over other windows so it is like
if the system also forgot the 3D window and associated shadow passed
over a zone and thus had to be refreshed (it does not happen with
shadow from a xterm, for example).

Yes. I removed all options except SubPixelOrder (none). Funny side
note: then it says using unsupported XAA and that I should use
EXA... in any case it does not matter about the 3D bug. I have been
trying both EXA and XAA in config file explicitly, so when it
complained, I assumed it was an old printf about forcing XAA (Firefox
scrolling is slightly faster with the "unsupported" XAA with "render
accel disabled" than with EXA; around FFv2 times it was clearly
faster).
I have been also trying other 3D apps, like Supertuxkart, and found
out the one running via PLib/SDL does not cause stacking issues, just
that in screenshots I get black pixels in zones covered by other
windows and the 3D content in non covered parts. STK from SVN does not
use SDL anymore... and the full bug appears.

With GART setting removed, I can see in /var/log/Xorg.5.log it selects
32:
---8<---
(II) RADEON(0): Using 32 MB GART aperture
(II) RADEON(0): Using 1 MB for the ring buffer
(II) RADEON(0): Using 2 MB for vertex/indirect buffers
(II) RADEON(0): Using 29 MB for GART textures
