This effect does not have to do with the UV beta. It's exactly the same in Run.GPS Trainer.
The problem here is the GPS signal. If the GPS signal is not very strong this sometimes happens. The position starts zigzagging around.
If this happens, it might help to disconnect the GPS and re-connect it again. The better the GPS receiver is the less likely it is that you encounter this problem.
