Hi we are experiencing the same or similar issue on two difference Vive setups in two separate locations. We have the leap attached to the Vive's headset and have verified both the hand tracking and IR camera feed pass-through are working correctly. Unfortunately if we attempt to use any Vive controller or tracker the leap device appears to be causing interference, resulting in the Vive devices jumping around. As soon as the Leap is disconnected then the controllers function correctly.
Has there been further issues identified or steps to prevent the issue since the original post was made? We were planning on using the Leap device as part of an upcoming project but will unfortunately have to look into alternatives if we cannot find a solution to the vive device interference.
