Hi ThinkGeo Team,
Our team found that we can zoom in and out to different levels and the location of the feature changes. We found that the issue occurred on several of the Bing map styles. Also we found that it did not do this issue on all the Google Map Types; only “Hybrid” and “Satellite”. In addition we found that sometimes even moving around the map caused the feature to move We are currently using Version 10 of ThinkGeo and more specifically version ThinkGeo.MapSuite.11.0.0-beta041 of MapSuite.
Here is a screen record of Bing Maps: https://www.screencast.com/t/qnhRAfW2f

Is there anything we are missing?
