are you sure this is a bug and real PCB doesn't do the same ? I see the same flickering on this video (which seems was captured from real hardware @60fps) near 5:11 https://youtu.be/rNHd0Y7J3Xk?t=311 one frame player's sprite above score numbers, another frame player's sprite is behind, and so on.
but, it is still the question why score number uses that unknown bit, perhaps a game bug ?
