[vtkusers] [vtk-developers] vtkAxesActor within VTK 7.0 and QVTKWidget

[Sankhesh Jhaveri]

Hi Luis,

I don't see anything obvious but I noticed that you are initializing
vtkRenderingOpenGL i.e. using the OpenGL backend. Mind trying the OpenGL2
backend to find out whether the issue is specific to the old backend.
