How about checking for integer color buffers in the state tracker and turning off blending (and alpha test) there? If you have integer buffers and try to enable blending with a hardware driver, does hardware typically no-opt the blend or does the driver have to disable blending? -Brian _______________________________________________ mesa-dev mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-dev
