i had this problem and i solved it ...
I went to the control panel / mouse
in the mouse properties parameters I ckecked the "display pointer trails" checkbox
Then i clicked on the "Apply" button.
I instantly could see the place of the cursor while moving it in a word document but ... disappearing again when stopping the movement.
This was a first step, partially solving the problem since i could see where i stood with my pointer.
I returned to the mouse setting parameters and i unchecked the "display pointer trails" ...
and ... surprisingly everything was ok again ... :-D incredible !!!
So this is something that worked for me ... that I hope that this stupid manipulation will work for people experiencing the same issue.
