harbour-pure-maps is a correct way of starting it. As I can see, we still have starting shutting down issue. Unfortunately, all I can come up with is to kill corresponding python process with a mighty kill command. I have no idea where to look for it as we seemed to cover many places already. Suggestions are welcome.

Maybe upcoming changes (Qt 5.9 in 2020) and Mapbox GL update (hopefully sooner) will help.

@mosen: thanks for the icons, will integrate them together with acknowledgment.
