Hi -
First time post, new MarbleWidget user.
I'm using marble library version 0.27.1 built with Qt 5.7.1 on Linux.
I've created a map widget which inherits from MarbleWidget and displays Bing-Map tiles (satellite imagery) of an airport runway.
If I create a GeoDataPlacemark, a set of Measure points or even just a custom paint graphic on the center of the runway, for example,
the placemarks, points or graphics don't stay at the original location as the tile level changes. It seems to be fine in longitude but not latitude.
As zoom level changes the graphics move (significantly) north off of the runway and on to other areas of the map.

Any ideas?

Thanks!
