Probably related.

Here's a GS dump people can run to see this issue. Seems to affect more than just Klonoa. Some trees in the first level also freak out when MTVU/IVU1 are disabled. Likely more models in later levels too.

I don't see the error in that picture? anyway, it's a core problem, a GS Dump is useless.

[coornio]

Yeah, I'm aware the GS dump doesn't do much for a core issue but I thought it might be helpful for people to have a better understanding of the corruption of colors and the whole flickering business that comes with it. Here's a zoomed shot for a better view:

I just tried Klonoa in both SW and OGL mode and I was getting the green color texture in the intro as in the original screenshot and also some weird textures - so unsure what's up. Latest build.

You probably have "Instant VU" disabled.
