Does that mean that there is no "preferred" way for double
buffering? So far I see two ways if dbe is deprecated:
1) Rely on the composite extension and a composite client to
redirect my drawing to off screen storage. Then send
damage reports after redrawing.
2) Create background pixmap. Problem: When should I free
the pixmap? Is there a way to create "soft-allocated"
pixmaps which the server can claim when it needs space?
I cannot find anything in the protocoll.
p.s. is this the wrong mailing list for this discussion? I
found some related threads which did not really answer the
question of double buffering:
"[Xorg] Damage/Composite + direct rendering clients"
"Does composition render double-buffering useless?"
