High Memory usage Mac App about coronatracker HOT 2 CLOSED

Can confirm this with Maps.app, crossed the 500mb mark easy only with a bit of scrolling around and zooming in/out..
Thanks for your investigation though!

Is this due to it being a catalyst app?

I suspect that in the beginning. I started by inspecting the app memory but found nothing interesting except the big blocks of memory allocated and not released.

After paying more attention to the used memory while using the app it was clear the memory is allocated by the map view. So, I removed it to make sure it's the culprit, and sure enough, the memory went down to under 50mb.

I thought it's a bug with Mac Catalyst, so I created a new project and only added a map view to the empty screen, and after running the app and playing with the map I quickly reached 300mb.

Finally, I wanted to see if it's only a problem with Catalyst apps, so I opened Apple Maps and just zoomed in/out to different locations, and in 15 seconds I crossed the 300mb line.

So, it seems to be an issue with macOS that affects all apps using the MapKit. Not sure if we can do anything here.
