polyline flickering

Whenever path is drawn polyline is flickering at the end. But when zooming in polyline seems to be ok. Looks like map is auto adjusting the polyline. Any solution?

Is this issue to do with he polyline approach or the overlay approach?

Issue with Polyline approach.

I am not able to reproduce this. Is there a video you could share?

This is an issue that we too faced before moving to overlay-based approach. Right now we are adding extensive support for markers on the overlay layer. I would suggest you try the overlay route which is much better.
