Extremely shaky camera in ARkit

I was just testing ARkit and the camera was very shaky, even when holding still the camera would every now and then jump around in the scene.
When testing other Apps they seem to be integrated into the world very well, even at the same lighting conditions.
Is that due to the ARkit plugin still be in beta or is there anything I could do to improve that?
Can I assume that will be fixed at some point and start developing?
