[Paraview] Polyhedral Cells: Rendering Problem with OpenGL...

Hi,
i found a rendering problem with cuts through polyhedral cells depending
on which rendering backend is used. For example in PV 5.1.2 compiled with
VTK_RENDERING_BACKEND = OpenGL
a cut looks like error.opengl.v5_1_2.png - there is a wrong shading and
some facets coming from the wrong starting point.
Switching to OpenGL2 everything is fine (error.opengl2.v5_1_2.png). This
problem is the same with ParaView 5.2.0RC1 and OpenGL or OpenGL2 -
however there seems to be an additional (smaller) problem using OpenGL2:
there are some lines drawn outside of the shell - see
error.opengl2.v5_2_0rc1.png (cutted on a different position).
The example cell is for testing is attached as "error.vtk" - cut e.g. in
x-direction on different positions to get the described effects.
Best regards,
Stefan
