It's hard to investigate without having a self-contained example, but there is
surely some threading issue.  The changeTimeSlice method uses non-local
variables, so when Render() is called in the EDT (event dispatching thread),
VTK pipeline may be modified by the main thread.  You can run everything
in the EDT to avoid threading issues, and if it solves your problem, you will
have to be very careful when moving processing out of the EDT.
