I have same issue, i think it is caused by: #130 when for every different zoom/region/positon of map are different anotations :(

I make video:

RPReplay_Final1610634992.mov

There should be always 34 annotations. mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) is called correctly, with correct clusters and annotations, but on map is not some clusters rendered

Also each minimal map zoom changes regroups all clusters

It caused by the fact that mapRects() method builds a list of rects dependant on a viewport

so, if you zoom to a level N, then zoom to a level N + m and then get back to the level N you won't get the same rect, hence you'll get different clusters/pins

is there any suggestion on how to improve this behavior?

ok, I was able to improve the overall picture by rounding the scale factor (

Cluster/Sources/Cluster.swift

Line 363 in 3c70568

let scaleFactor = zoomScale / cellSize(for: zoomLevel)

) to the nearest non-zero digit. the function that does that can be found at https://stackoverflow.com/a/32194113/5247504
