I've got a Mac with MacOS 10.13. When I'm in a video call with shared content (e.g. desktop or presentation) I get the second window open up, but there's nothing in there other than a green background. Looking at the call stats, I can see my Jabber client receiving the second stream.
I've tried 11.9 & 12.0 Jabber client with the same result.
If I use a Windows computer (with the same Jabber account) then the shared content displays fine. If I use another Mac, that's fine too.
Any suggestions on what's wrong or how I can fix it?
Thank you.
