[Paraview] Noise after use of a clipping box

[Patrick Brockmann]

Hi all,

I try to clip an unstructured grid (layers on a sphere) with a box.
I was expecting clean planes from the clipping planes
defined by the different faces of the box, but I get some noise
(small cells along the vertex of the clipping box)

Is there an explanation to this ?
