I am trying to use both `vtkGenericOpenGLRenderWindow` (providing glfw and glad) and `vtkRenderWindowInteractor`. I get this crash when initializing the interactor:

VTK is built from source so it doesn’t sound like an ABI problem.
Any clue on the possible cause of the problem?
Note: running on debian with VTK-9.2

Looks like a graphics driver issue. Can you run other OpenGL programs?

Yes.
I used glad and glfw. So, I tried to drop them and prefer using “VTK::glew” and “VTK::opengl” (but keeping glfw).
Still crashing but in slightly different way:

Am I supposed to pass the GLFW window to `vtkXOpenGLRenderWindow::SetWindowId`?
If yes how? (not clear to me)

No, VTK creates its own X11 window. Do you have a valid X11 display? On linux, VTK supports XLib as the only own windowing platform for now. If you’d like to bypass creating an X11 window, use [offscreen rendering](https://vtk.org/doc/nightly/html/classvtkWindow.html#a193ffdb82bfd6c54b6830250dd06e4d7) or use [vtkExternalOpenGLRenderWindow](https://vtk.org/doc/nightly/html/classvtkExternalOpenGLRenderWindow.html#details) to render into a GLFW window.
