[vtk-developers] OpenGL2 and Windows 8.1 - how to disable vtkRenderingOpenGL

[Aashish Chaudhary]

Typically this could happen if you have rebuilding VTK with OpenGL2 backend
and early on at the same location you have built it with OpenGL backend. I
believe the problem could be related to Cache. Try building VTK from
scratch with OpenGL2 backend and see if it goes away. You can also try make
rebuild_cache.

Thanks,
