Including a photo below, as I'm not sure how to describe this exactly.

We're using MKPolyline to draw a line on a map in an iOS application. After drawing the line, the user can zoom in or out on the map.

After zooming in, occasionally, the following artifact/pixelation can be seen, usually toward the outer bounds of the line.

Any thoughts/suggestions on what is causing this, and how to fix it? Any information would be appreciated.

I've seen some of the same on close zoom ins, more often on annotation points but also on polylines. Not sure why / haven't addressed it yet, but you're not alone. – Ron Diel Nov 02 '16 at 23:44

Seems to just happen with iOS 10. Maybe, Apple will fix it in iOS 11... – who9vy Jul 17 '17 at 14:06
