Describe the bug
The polyline segments sometimes do not display when updated.

To Reproduce
Steps to reproduce the behavior:

1. I added a button that, when clicked, adds the center point of the screen to the route.
2. When I add center points in different directions, sometimes the line segment in one direction doesn’t display. Only after adding a few more points does the line segment appear complete.
