Edit Reason: Gimp needs an image open to show this.

I don't know, it just made me think of a used laptop about 15 years ago that was doing this and the fix was to replace the touchpad. This was a Dell. Apparently the A/D converter that converts the location you touch to numbers can develop drift. But this was affecting where the cursor was left on the screen.
Try a program like Gimp that reports the cursor position as x,y coordinates and see if those are changing. (Open an image file or do File->New to make a blank one) . I see the Pine Store now sells some parts, I don't remember if there's a touchpad there. If you have access to a DrOk you might watch the power supply voltage for a few minutes, drift there might cause cursor movement.
If I'd just gotten one new that was doing this I'd try to talk support out of a new touchpad especially if the numbers were drifting.
