I have Fedora 34 Workstation and I cannot properly share screen on Microsoft Teams with Google Chrome.
If I share the entire screen, both me in the preview and the other participants after I share see it fully black, they only see a black box that fill all the screen.
If I share a single windows it works now and then. But, in this case, if I stop sharing and then re-share another window, participant still see the old window, even if I closed the application that generated that window in the meantime. To change window I have to exit the meeting and re-enter.
Plus I cannot share the window of some applications like Master PDF Editor.
