Dear @faddi,
while I don’t know if that will help in your specific case, you might be successful with the Worldmap fork we are maintaining at GitHub - panodata/panodata-map-panel: Map Panel for Grafana with improved convenience, robustness and features. Friendly fork of the original Grafana Worldmap Panel. Currently not maintained, but verified to work up to Grafana 9.. We just published version 0.15.0 including many improvements from the community and our own pen.
We heard from other users that it works fine on Grafana 7.x in general. On this matter, we will also be happy to hear back from you whether this might already resolve the issue you are observing.
With kind regards,
Andreas.
