White bar on top of Windows Explorer and browser apps on Windows 10

[BetaTime]

We have a few users experiencing graphical issues.

 

Sometimes they have a white bar on top of their Windows Explorer and their browser apps.

 

A temporary fix for the browser apps is pressing f11 twice.

 

But is there a permanent fix?

 

We are connected to a local domain. (No Azure or something)

 

I am one of the IT guys here.

 

Till now 4 of the 100 have that problem.

 

They are running build 10.0.15063.1266.

 

Al drivers are up to date.

 

And it only happen on web browsers and sometimes the file explorer.
