Just noticed this today after i swapped some USB hubs on my setup in an effort to clean up my desk. Went from a Targus USB2 octopus hub to a UniTek USB3 hub and suddenly started getting jitter and stutter on the Microsoft wireless mouse i have here at work. Swapped back to the octopus and no problems This got me wondering whether the same jitter and stutter issue at home with my Logitech MX Master was not an issue with the wifi (as is often blamed) but with the USB3 hub it was plugged into. Swapped it over for a no-name USB2 hub and suddenly no issues at all. Anyone had similar issues with USB3 hubs and unifying adapters (i.e. not BT)?
