There is some memory leak in version 0.4.1. The number of FPS successively decreases with each successive run between the terminal stops. The first run has between 50 and 60 FPS. On the return run, the FPS drops to 40-50. The next run is 30-40 FPS. And so on. To get back to 60FPS I have to go back to the menu and select the route and tram again.
