### System information

- OS: Fedora Workstation 34
- GPU: NVIDIA Corporation GM107M [GeForce GTX 860M] / Intel® HD Graphics 4600 (HSW GT2)
- Kernel version: 5.11.16

Issue started after upgrading to Paraview 5.9.0. I wrote bug report against Mesa ([https://gitlab.freedesktop.org/mesa/mesa/-/issues/4729](https://gitlab.freedesktop.org/mesa/mesa/-/issues/4729)) and Mesa developer Marcin Ślusarz found bug in one of VTK shaders (see discussion in Mesa issue tracker).
