It would be possible but it would require destination alpha for translucent windows and I really don't want that to be a requirement. It's usually very easy for us to know the order of all windows so designing the drawing code so that a depth buffer and destination alpha isn't required makes a lot of sense to me. - David _______________________________________________ compiz mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/compiz
