Does Option "DisplayPriority" "HIGH" in the device section of your config help? Also, if you have a large virtual setting in your config: Virtual 2304 2304 reducing that might as help as well if you don't need all of it. And finally, you might try disabling tiling: Option "ColorTiling" "FALSE" Alex -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
