Description

This boss in Catlevania Dawn of Sorrow(game code NTR-ACVE-USA) has an issue where the overlap of the arm segments near his elbow will flash black.
236331261-87d0df0e-3f58-4413-89c5-d1a4cad33250
Affects both the software renderer and OpenGL renderer. I've verified that it does not happen on real hardware.

Here is a save file right before him. He's to the left of the save room.

Research direction

Start by loading the attached save file for Castlevania: Dawn of Sorrow and reproduce the black flashing at the boss's elbow in both the software and OpenGL renderers. Compare the behavior with real hardware; done means the overlapping arm segments render without flashing in both emulator renderers.
