[vtkusers] Fwd: VTK + PyQt5 + VirtualGL not working

[Felipe Bordeu]

Hi everyone,

I can confirm this problem. I have a python 2.7 + qt4 + vtk working app on
a remote server with vnc for the visualisation. But with python 3 + qt4 +
vtk the same error message appears. If I test the vtk installation alone
(not in a embedded qt window) I can create a visualisation in a window.
