Overlapping Clusters despite high clusterRadius

Question

Hi everyone,

I think we're seeing a bug with feature reduction, where in some rare but consistent places, the clusters overlap at certain zoom levels, despite having a high clusterRadius configured (150px):

These are "real clusters", not ghost images as other people have reported on this forum, which we've also seen on earlier versions of arcgis js. Overall clustering behaviour seems to have been generally improving over the last few arcgis js versions, but this one has been lingering, still happening on 4.22.0.

Is this happening to anyone else and do you know any way of going around it?

Thanks in advance!

Paulo

You can test it out using https://js.arcgis.com/next/

This should be fixed in the next update of the JS API (v4.29).

Ah yes. That is a known issue. Some of the clusters are broken apart on tile boundaries. We have an open ticket for fixing this, but no timeline has been set for it. I'll link this thread to the issue. Thanks for bringing it up again.
