Using 'NoAccel' in xorg.conf seems to hide the symptoms of the bug, or remove the bug. However, without that option, with this patch, the problem seems "less bad", if that's even possible. It takes longer for the root window to get "ridiculously speckled." Not sure if that info helps at all. :-) Not sure if I mentioned that, the first patch (the one sent a couple weeks ago) did not seem to have this problem. Thanks, __Armando Di Cianno
