VTK: Rotate actor programmatically while vtkRenderWindowInteractor is active

I'm trying to rotate a vtkActor using vtkActor::RotateZ and then calling vtkRenderWindow::Render. It works fine (it rotates the actor) but I can't move, resize, or even focus the window.

I suspected this was caused due to something not catching operating system events, so I added a vtkRenderWindowInteractor to the mix. Now I can move, resize and focus the window, but the actor is not rotating anymore.

I've isolated the code in the snippet below, comment line 43 to see both effects:

renderWindowInteractor->Start();

I'm compiling VTK 6.2 with mingw-w64 (GCC 4.9.1), running in Windows 8.1. I've uploaded the code in this repo with a small CMake setup so you can test it easily.

Thanks for your help!
