Screenshare not working because of SharingIndicator

vteivans commented 2 years ago

I'm having an issue with screen-sharing, maybe someone has some ideas how to fix or at least debug this?

During a call, when I press on "share screen", no windows or screens are provided. However If i do it through chromium browser (also installed through flatpak) it works. After some debugging I got to these errors in Teams Log:

warning -- sharing-indicator loading from 'slimcore/lib/sharing-indicator' error -- cannot instantiate SharingIndicator info -- createInstanceAsync: SlimCoreInstance settings {"enableLogging":true,"enableSlimCoreLogging":true,"enableSlimCoreVersionCompatibilityCheck":false,"tsCallingVersion":"2021.48.01.1"} ****
<2> -- info -- sharing Indicator is not enabled. Not setting up local screenshare.

I can't find any logs on what is exactly failing.

Same behvaior as described by vteivans on Fedora 35 (Wayland Session and Gnome). In earlier versions Teams screensharing worked with Fedora 35 flawlessly. It broke around start to mid of february afaik. It seems that other applications like Jitsi had similar problems for a while - eventually those were related?

I did some investigation and it turns out that this issue is caused by the Electron version MS Teams use. It doesn't support wayland and with it the screen sharing. And as I understand it - it works in backwards compat "X11 mode" on my wayland GUI.

And according to tickets I've found, MS doesn't plan to upgrade the Electron - they're switching to Edge WebView 2, which is does not support Linux for now (https://github.com/MicrosoftEdge/WebView2Feedback/issues/645).
