Problem with polylines near north pole #8

If you click on Kentucky first and then click on China, the greater circle crosses the north pole, but the line is rendered across the top of the map and crosses itself.

Do you know of an algorithm that would render the polyline as more of an arc?

I would be more than happy to address the issue but I do not know where to start looking.
