Also having the same issues as mentioned in this thread so far. Seems to have gotten worse after trying to revert back to old software as well. (but that may just be my frustration in noticing it)
Also, as others are pointing out, am noticing several duplicate devices.
Mouse was purchased in UK, currently in Portugal.
Have noticed the issue for the last few months, mostly whilst playing games (I daren't play any FPS now) but now also noticing in other software like photoshop or even general browsing and use.
