Not sure what all these tables affect, but I've had no end of trouble from nouveau supporting BGRA4 sampling but not rendering - the latest fail is doing a copy image from a "BGRA4" renderbuffer (which gets upgraded to RGBA8) and a BGRA4 texture. But also (buggy) applications get weirded out by being unable to render to a fb with a BGRA4 texture attachment. -ilia _______________________________________________ mesa-dev mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-dev
