I have the same problem. Though in my case it is a small unstructuredgrid
vtu file. The OS is Ubuntu 14.04. ParaView-5.0.0-Qt4-OpenGL2-MPI-Linux-64bit
prebuilt binaries. The Graphics card is Nvidia Quadro K620 with OpenGL
version 3.02 Nvidia 352.63. The Nvidia settings show the following etensions
amongst others GL_ARB_frame_buffer_object.

Also, it does show artifacts. In particular for a vector allocated to a
standard hexahedron cell, the colors are slightly different within the cell.
You can see triangular segments [possibly tetrahedron?]

It seems to me that you are running into a different issue as atleast
you are seeing
something but it does look correct to you. Is that it?
Thanks
