Mario vs Donkey Kong: Mini-Land Mayhem minor visual glitch #1962

Open Jaklyy opened 5 months ago

Jaklyy commented 5 months ago

the first scanline in the Construction Zone Menu is glitched the main background image is rendered using the 3d engine (for some reason?) disabling textures results in the gap at the top of the screen being hidden, so presumably the actual polygon is rendering fine, but the texture's alpha is showing erroneously. Only occurs with the sw/compute renderer. image

update: upon further investigation i have diagnosed this as a bug with the way clipping interpolates attributes ...which means the classic opengl renderer is probably doing something very wrong if it's getting a correct result out of incorrect inputs
