I've just compiled and installed xorg 184.108.40.2062 with the gentoo ebuild in
portage. Everything seems to work on my radeon 7500 (open source drivers) even
if with transparencies the system is too slow to be usable, but there are two
problems with opengl software. Performance are better than with previous stable
release (+10% fps), but with xcompmgr enabled:
1) slowdown and framedrops occur every few (random) seconds: if I launch
xcompmgr with option -n there are occasionally black zones that cover the
surface of open windows on desktop (for example the console I use to launch the
program) and with xcompmgr -a there are just the slowdowns
2) menus appear for an instant and are immediately covered by the graphic (this
happens for example with celestia); it seems that they are drawn only when the
mouse passes over them

i can confirm this bug in a nVidia system with latest drivers. performance is
good, but menus and windows are covered by any OpenGL app.
Do you still experience this issue with a current release of xorg?
Still experiencing (2), (1) seems to be ok now (xorg 7.0)
Modifying this entry to reflect the cause of (2).

I don't think this is really a duplicate, reopening.
http://dri.freedesktop.org/wiki/DirectRenderingToRedirectedWindows has a rough plan for fixing this. Work has started but will take a while, so don't hold your breath.
