When doing slices and clipping of 3D meshes (specially unstructured meshes), when one turns on the surface with edges representation. paraview shows a lot of parasite edges that are not there in reality, an example of this behavior (cylinder mesh generated by snappyHexMesh from OpenFOAM library):

the issue (specially for new commers) is that one thinks there are this edges in the mesh and thinks ‘something went wrong’, where this are artifacts from cliping/slicing, if one sets to crinkle view this issue is not shown:

Ideally it would be nice to not have this parasite projected edges that they prompt to confusion, even in non crinkle version but I think this would be a lot of work (and not evident on ‘how to’ implement it) nevertheless simply having crinkle by default would be better…  
also same mesh (with same clip) but from a normal view with 2D representation:

this is a question that at least in the OpenFOAM community comes quite frequently with new users.
