Green Slime
Me and my friend recently started the game again from scratch and managed to kill the Giga Slime in the arena. I was dead, and my friend managed to land the last hit at the same time that he died, so the "Continue/Quit" screen appeared while the cutscene continued in the background. We managed to get past the cutscene, and ended up with the black and white screen. Changing instance/world didn't fix it. Save and quit and starting up the load again managed to fix it.
