I couldn't reproduce the infinite loop you mentioned, it's probably a driver specific symptom when the interactor is used uninitialized. Your best bet is to initialize the interactor before doing any rendering. I'm not an authority on the use of this class but the examples I looked at all did this.<br><br>ParaView is using the VTK master branch which has the gl error checking.
