This worked to enable the screen-sharing button in zoom for me, but now I’m noticing that not all of my application windows get shared properly. E.g. sublime text and tilix do not show up in the video feed when I enable screen sharing. It’s like they just don’t exist. Any idea what’s going on here?
I notice something similar when trying to screen share from a browser with talky.io or google hangouts. In Chrome, if I choose “share entire screen”, the entire screen I share is black, except for my mouse pointer. I am able to successfully share the location of my mouse, but that’s it 
Sharing a browser window seems to work, but I can’t share any other application windows, and I can’t share my entire screen.
