Psychonauts strange rainbow artifact in Milla's Dance Party level

[BParks21]

Describe the Bug

When traversing Milla's Dance Party there is a strange rainbow artifact that can be seen on the wall as the disco ball is rotating. It occurs in both HW and SW mode but looks different in each mode. I'm not sure if this occurs on real HW or not. I tested the native PC port and this artifacting is not present. It doesn't look intentional but who knows maybe this was a PS2 specific issue. The source of it is the disco ball rotating in that area of the level but looks wrong.

Reproduction Steps

Get to Milla's Dance Party level and explore the same area in the dump.

Expected Behavior

I would assume not seeing these artifacts on real hardware.

can i have a memcard from around when this happens , since real hardware needs to be checked

[BParks21]

Yeah I'll upload one when I get home. @Mrlinkwii I'm using a folder memcard is that fine? Or I can create a save state you can load that then save.

Here's a state and the memcard.
