Elements are floating around

Hello everyone 🙂

i am currently working on a project with the adobe aero geospatial prerelease. My goal here is to walk on a virtual path. My problem is that the elements are not fix in their position and are moving along as I walk (you can see it in the video). Does anybody know if there is any solution for this problem or if the tracking in aero is just very inaccurate and I have to deal with it. 

Thank you!
