The keyword being 'reduce'. This won't reliably prevent tearing in general, so I'm not sure I see the point of jumping through all those hoops. If glamor Xv used (something like) present_pixmap(), that would reliably prevent tearing at least in the fullscreen case, wouldn't it? If you don't want any tearing ever, use a Wayland compositor? :) -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
