ola, cyrille,

well, yes it's obvious i'm almost new to gem, but
things are getting better and worse
( see attached patch ) :

i do it now at each cube rotation,
what i get is a double rendering
in double buffer mode
and still _no_ rendering in gem window
in single buffer mode ..

_but_, one thing is better, i get frames captured
in pdp window in single buffer mode,
that's the only mode that works with a pdp_xv

something is wrong in my patch now?

yeh here you're right

ciao,
sevy
