PROBLEM DETAIL
I have the same issue on my Toshiba Z20.
My son has the same issue on his laptop.
We had a consultant at our work yesterday and he had the same issue.
There are a gazillion people all over the internet with this problem.

 It's only MS word. It's not power point or excell. No other programs. not libre office.
 Not my video editing program.
Not thunderbird mail.
Not any browsers (Edge, IE, Firefox, chrome)
It's only word.

I have to my knowledge all the updates from windows update.

The interesting thing is that when I go to device manager and look at the driver details for the laptops inbuilt screen I get a different driver than for the external monitor. We seem to have two things in device manager
