I have exactly the same experience, a controller, currently it's the left, doing weird things with heratic movement.
I also tested with three PCs! 2.0 and 1.0 stations, with various Valve index and Wands controller sets.
I also checked several setups, covered all surfaces likely to generate a problem ..
But still at the same point, and my vive pro has already made 3 trips for nothing, because the after-sales service does not find anything abnormal in their tests and therefore does not take any action each time.
I also signal that I have a Vive OG which has no problem with the same base stations and controllers ...
That all.. , I crack, I do not know what to do.
