For what it’s worth I have this transparency problem too: [Problem with transparency with VTK \>= 8.0 on Linux](https://discourse.vtk.org/t/problem-with-transparency-with-vtk-8-0-on-linux/3309/6) . Opaque objects render fine but the moment that opacity is different from 1.0 they disappear. In my report I talked about Mesa versions and mine being possibly too old but it looks like you reproduced it with Mesa 20.1.8, so I don’t have any other leads at the moment, unfortunately.
