That empty message was unintentional. This patch was made when i was under the impression that someone was hitting this problem. Now i realize it is something else that is causing serious issues. I still stand by the patch, because i do believe an additional composite operation is far cheaper than falling back. That said, i'll try putting together a testcase in the forseeable future. _______________________________________________ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
