Screenshare only works with active webcam

Hello,

I made a new installation of Jitsi in my own server this week and I’m using the iframe, but I’m getting a strange behaviour this time.

  1. If I want to start a screenshare, It will only works if I share my webcam too, If my webcam is not turn on, my screen won’t appear to other participants.

  2. And I realize too at least on google chrome, that I can share my screen as usual if there are no more than 3 persons on a meeting. If I share my screen but a third person enter the meeting, my screen will stop appearing to all participants, and then I need to start my webcam to continue sharing my screen.

On the browser console no erros are shown, can’t figure out why.
