Hello,

I noticed that the current horizon client does not export its screen over
eg. MS Teams. You only get a black screen.

Steps to reproduce:

- Use windows with 8.4.0 client
- connect with it to a linux desktop
- Share the linux desktop with eg. MS Teams with coworker "Bob".

Result:

- Bob does not see the linux desktop, only a black screen

It works with Horizon client 8.3.0.
