Describe the bug, what's wrong, and what you expected.

Since migrating to tox, the render window in the report is showing as abstract. This may have been because the reports were previously generated after running tests. It seems triggering the rendering pipeline is needed to "activate" it somehow.

from vtkmodules.vtkRenderingCore import vtkRenderWindow
print(vtkRenderWindow().GetClassName())
# vtkRenderWindow

import pyvista as pv; pv.Plotter(off_screen=True).show()
print(vtkRenderWindow().GetClassName())
# vtkCocoaRenderWindow

Steps to reproduce the bug.
