Hi all, I wish you helped me.

When visualizing a mesh in ParaView, there's an option to enable the VTK Polyhedron: what is this feature?

I've noticed that enabling it creates sometimes shaded areas that look like there's a negative volume or something like that, but when I choose not to enable it, the shaded areas disappear leaving place for a more regular cell pattern. Is it just a rendering problem or what?
(I'm going to attach two examples)
