Touchscreen on 2-in-1: cursor sometimes changes from arrow to hand making system unusable
I have a 2-in-laptop. Whilst in "tablet mode" and using touchscreen gestures sometimes the cursor, and I'm not sure what exactly I am doing to cause this, changes to a hand*. I am then unable to use the system (because touching the screen then does nothing) unless I unfold back to laptop mode and use the Esc key to get the cursor back to an arrow.
One way I can get this to happen quite easily is to repeatedly use a four-finger swipe (which should really be a three-finger swipe, as it is with the touchpad) to go in and out of / move within "Activities".
*To clarify, I cannot see the cursor while in tablet mode. I can only tell that it has changed when I go back into laptop mode and use the touchpad. Whilst in tablet mode the keyboard and touchpad are disabled, as they should be.
