I assume you are using QVTKOpenGLWidget, we use this directly in
Tomviz for a few charts that control color/opacity too. This should be
handled in the QVTKOpenGLWidget, but it is possible an initialization
bug has crept in. I have noticed that ParaView often doesn't see this
issues as much due to resizing Qt widgets several times on startup, I
will see if I can get some time to test the latest Tomviz (we had this
working, but I haven't been tracking VTK master as closely these last
few weeks).
