I use Teams in Chromium and since updating to Fedora 43 I cannot share my screen any more, it’s just black and what’s more, I cannot even see the screen other people are sharing.
I was using Arch Linux up to last week, and I had X11. I understand I am forced to use Wayland with Fedora, which is fine… but I really need to be able to share screens, how can somebody do this in Fedora?
Which Edition / Spin of Fedora did you install (i.e. which desktop environment are you using)?
Thank you Fabio. Fedora 43 workstation, using Gnome. I was using Gnome also in Arch Linux.
Hm. This is definitely supposed to work … but it’s hard to tell, because Microsoft Teams doesn’t appear to show your own shared screen (at least if you’re alone in a meeting). I tested Google Meet and that worked fine in Chromium on Fedora 43 Workstation. Sorry that I can’t be of more help right now 
Is it worth to test another browser? E.g., Firefox? In order to verify if the issue is related to the browser? Just to avoid false assumptions 
I use Teams regularly on Firefox without issues, including screen sharing, though I use KDE.
Supplement: I added some tags (to gather awareness of screen sharing experts 
)
It’s definitely more complex than just a Teams issue. For example, with Slack I can share a single window fine, but if I try to share the whole screen… black. If somebody knows any troubleshooting steps, I’d welcome it, as this might force me to have to abandon Fedora - this is a fresh new install, so not sure what cloud be happening.
Screen Sharing broke for me as well after updating to Fedora 43.
I just wanted to report that avoiding flatpak and installing native RPMs solved the screen sharing problem. I do like the idea of flatpak, but ti cannot possibly be the default at the moment, it’s badly broken with Wayland.
This made me realize that I asked what Edition / Spin of Fedora you’re using, but didn’t ask to clarify whether you’re using the Chromium package from Fedora (I assumed so). 
Knowing that the problem occurs with the Flatpak and not with the Fedora package would have helped narrow the issue down.
I didn’t realise myself. Flatpak seems to be the default when you install via the Software manager. I am erasing all flatpak from my system, video doesn’t work at all, like if I install vlc it can’t play anything.
it’s annoying flatpak is being pushed down people’s throats when it’s not ready.
