Perspective map markers stuttering when selected

In the Perspective app I’m working on there is a map with about a hundred markers. The map purpose is to select a marker on the map and being able to click on a button at the bottom of the maps to open Google Maps and drive to that point.
My problem with it is that every time I touch on a marker all of the markers on the maps appear and disappear for a second or two and sometime the marker doesn’t even get selected, so the map this way is very difficult to use.
I just test it on the browser and on it there’s no stuttering.
Is this a common issue with the perspective map or it could be a problem with the event script?
