my system:

vtk version       : 9.0.1
python version    : 3.8.5 (default, Sep  4 2020, 07:30:14) [GCC 7.3.0]
system            : Linux 5.4.0-72-generic posix x86_64

Interesting. What program are you running here? Do you get this black window with any VTK test program?

Yes, all examples give a blank screen in vtk9.0.1 (Ubuntu 20.04.2 LTS).
Version vtk8.1.2 works fine.

Also paraview works ok, but i’m not sure what vtk is it based upon.
