Maybe that’s caused by electrical interference. When plugged into the Mac to charge, it works like a wired USB device.I'm hoping they fix the random stutter/delay/jump on the Magic Trackpad. New M3 iMac and right from the start during set up it was doing that. It's a little better now but it's still there.
My wife and I both use magic trackpads with no issues. I keep mine plugged in but my wife doesn’t.
