Maps don't render if they are not the default tab

I've installed QuickTabs and am using it to create three tabs, each one is a different view of the same data. One of the views is a views Geofield Map. Everything works fine if the Map is the default tab. However, if the map is NOT the default map, then it does not render when selected. Rather, I see a large gray block in the place of the map (see attached image).

I've tried using both Geofield Map and IP_Geolocation to render the map in views, neither of them work.

I've tried with AJAX on and off (settings for quicktab), but neither work. I've turned AJAX on in the view to see if that would help, but it does not.

If the map is not the default image, but I zoom in or out on the page with the browser when the map is visible, the image renders.

Any thoughts or suggestions?
