I have a Google Map, built with the JS API, that has polygons for different regions of the UK.
On Chrome (v58 and v60 tested) when the user zooms in or out with the scroll wheel random artefacts of the Polygons are getting stuck on the map.
Zooming further either removes them or shows different artefacts.
This does not happen in FireFox.
Anybody experienced this before and found a solution?
