Advanced visualisation flythrough issues

I am trying to create a flythrough trajectory for visualisation of point clouds. I have looked at the example but having no luck with it. Is the example broken? I do not seem to be able to get my point cloud to move.

I do get the following warning print out though:
[Open3D WARNING] [ViewControl] ConvertFromPinholeCameraParameters() failed because window height and width do not match.

This is on v0.10
