I have a 2020 MAc book Pro and a Wacom Intuos Pro tablet. I´m working with Illustrator 2020. A few days ago I started experiencing a very annoying problem while working on AI, the artboard suddenly moves (as if I were using the panning tool) to one of the sides or across, it moves slowly and I can´t do anything until it stops moving by itself, it is now happening very often which makes me lose a lot of work time. I thought it may be something with the Tablet so I uninstalled averything and re installed, but it keeps happening. I just upgraded my OS to Big Sur and it didnt fix anything. Driving me crazy! It happens with any sized files, even whith very simple small ones.
