Huum, the alpha being premultiplied or not seems to be a property of the framebuffer to me, not of the plane. It seems to me that we should define alternative premultiplied DRM_FORMATs and make the sprite planes advertise support for premultiplied fbs in the format list when the hardware indeed supports them. -- Damien _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
