Hmm.. There shouldn't be a problem with tearing in xbmc for intel cards. Atleast I don't have it anymore. I have noted that if driconf is set to always wait on blank, on some systems we end up waiting twice (just set it to driver select in settings), but otherwise there shouldn't be a problem. Then again, I've not tested master of current xorg/xserver/dri. But hardy/gutsy versions work just fine. The only issue was that we have to force a glFinish() before swapping in case of driconf set to always wait, since driver seem to wait for vblank then flush/finish opengl commands which makes it often miss the vblank. And no we don't use xv. Regards [email protected] _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
