On map panning, resizing and zooming in both Split and Swipe modes a terrain "jittering" is often present.

Quite honestly I'm not sure there's an easy fix as it seems to be inherent to the Mapbox base style that I used to create the custom one that's utilised in the project.

A good first step is to try a Mapbox's own maintained terrain style and see if it can be reproduced with it.
