We had a longstanding problem with this but recently sent our Lenovo AIO computer for a repair (replacement motherboard). It has worked fine since we had it returned until the Windows update last night 20 March 2021 at which point it resume phantom touch or bubbles on our screen. This can eventually be turned off via Device Manager HID Touch Screen - disable but I do not want it to reoccur every time we turn the computer off or have an update.
