Backing store has long been off by default in Xfree/Xorg. Fundamentally its a dumb design issue in the concept of backing store - it means the server has to consume huge amounts of memory keeping copies of stuff and if someone massively resizes a window with backing store (remembering it can be mostly offscreen) your X server explodes. Backing store was mostly a mistake at the time of introduction (as opposed to save unders which are a least reasonably resource bounded). _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
