MapMarker floating away from its position when zoom in/out or rotate map

[bentmar]

Like the title says.. I am using the default marker image, seems like the reference point of the marker image to the location on the map is outside the image itself.

Tried both with and without popups, with different MapControlAlignmentTypes, no difference.
This problem is not as major if I go with the stable nuget release (but i need popups so thats not an option). I am using the prerelease nuget right now.

Thank you!
