Well, I mean color glitches. But it isn't consistent. As if some operations operate with the correct byteorder and some don't. alpha/blue being swapped is a problem in some areas. https://www.kraxel.org/tmp/ cheers, Gerd _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
