A family of Microsoft word processing software products for creating web, email, and print documents.
I have the same problem (still not resolved) along with other display problems. All took place after a Window 10 update to version 1709 on December 23, 2017. I have a Dell XPS laptop connected to a docking station and two monitors. It was fine before the update, but now window size are disrupted all the time and the cursor problem started happening. See below for other the other display problems - large fonts.

Welcome to the club! Sorry you had to be here...
I haven't noticed the font issue -- it looks quite annoying.
In your photo above, what does the "Change your mou..." on the menu really say? Any chance it's a mouse driver? I'm asking to see if it relates to my theories as to why we are having these issues.
Thanks!
