Zbrush: Colour pixel artifacts in polypaint - issue with subdivisions

Fallen Creation

So I'm currently polypainting a model, I've done this process many times but never came across this issue before.

This is it on subdivision 4:


And this is it on subdivision 8:


It looks like a bad image compression or something. Even if I fix the polypaint up in the highest subdivision if I scrub up or down on the subdivisions the artifacts appear again...

Any ideas why? Thanks

Uhh yeah it does look like compression...but zbrush shouldn't do that. What matcap are you using?

Both SkinShade4 and flat color.

Scrubbing alone shouldn't do that, although smoothing the polypaint at a lower level would.
