<br></div>Our app is running with wxVTK and wxWidgets, so I'm wondering if there's an issue there somewhere. I'll ask on the wxVTK list. Unless you've any other ideas I'll try to recreate the problem in a VTK-only window and get back to you.<br>

Above a certain threshold of complexity, panning (holding down shift and left-dragging) will stop working properly. With more items the scene can no longer be dragged around far enough - it feels like it is has got heavy and stays in the middle. With even more items the panning actually pulls in the opposite direction. Attached an image of such a scene - it's pretty reasonable and renders reasonably fast.<br>
