Transparency is OK with nvidia driver (256.53-1)  but does not seems to
work well with nouveau driver (windows don't stay black like they used
to be with nvidia, but the display is not ok though, there is sometimes
a latency and windows get black). More precisely:

vesa, nv: no transparency at all. No black windows though.
Afaik, transparency should not depend on glx extension... nad then
should wok with nv driver.
nv specific issue: menus appear with a sensible latency and look
inoperant (i could not close kde session)
nouveau: temporary black windows when resizing or
moving. Transparency looks almost ok, despite of this little latency but
for some reason i cannot check more right now any further (trouble
with direct rending manager).
nvidia: transparency is ok. Windows get translicid when moved or
resized and are correctly displayed and decored - no latency, no black
window.
