Playing around with blending modes in pygame 1.8.1, it seems that BLEND_SUB doesn't work properly. It looks like the blue channel isn't getting updated. Is this a known problem? Should I file a bug report?
Hi Greg,The blend modes in 1.8.1 were incomplete and untested, especially for 24 bit-per-pixel surfaces. They were completed for Pygame 1.9.0.
