Most 3D hardware has the same limitation; however, I'm not sure all hw drivers check for the case properly. Ideally the render spec would not have required alpha=0 when sampling outside the source region. > > We really don't want to hit such a slower-than-software fallback.

Software fallbacks are almost always slower then pure software rendering since you end up ping-ponging between hw and sw rendering. To be fast you need either all hw or all sw. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
