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?] Regard Paul. _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview
