[vtkusers] Problem with volume rendering inside of Qt application

[Aashish Chaudhary]

If you are using older version of volume mapper (OpenGL backend) then it is
possible that when using QT window, it's not finding the extensions its
needed. Is it possible for you to try the OpenGL2 backend?

Also, Do you see any error message on the console?

Thanks,
