Google Map shows only partially

Question

The Google Map I have is only beeing rendered partially and is centered to the wrong point (it should center to the marker). See below:

Answer 1

Opening console doesn't re-executes any JS! The page size gets changed by it, Google map API then fires 'resize' event and loads the map again.

I faced the same issue when setting the map centre manually. I solved it by the below code:

google.maps.event.trigger(map, "center_changed");
