Onenote for Windows 10 Share Screen zoomed in

[simpsonj]

Slightly odd one, but due to it's nature, difficult to Google.

 

Essentially, whenever any member of staff clicks the share button on a Onenote for Windows 10 onenote on their laptop, the share window is really zoomed in. It must be a scaling issue, because if I do the same on an external monitor, it's show absolutely fine.

 

There is a work around (hold ctrl and use the mouse wheel to zoom out), but I wondered if anyone else had the same or similar issue, and knew how to resolve it?
