Problem seems to be with the scale of the object. Possibly rounding errors and not a bug? Visually it still looks odd, and could perhaps fail more gracefully?

Managed to see the issue even after applying scale, so not sure what's going on. Removing duplicates does not help.

Ok, I just made a new very similar object from scratch, and everything was fine until I assigned the Grey Soft material to one of the mesh bodies inside the object... that material is literally a default material with a changed viewport color. I do not understand what is going on...
