Hi all,

I've been hoping this was a temporary issue; but...

A few months ago (roughly), I suspected as the result of some updates,
screen sharing during video conferencing stopped working. The problem
affects every possibility: Zoom app, also WebEx, Jitsi, MSTeams on
browsers (Firefox, Chrome).

When I click a Share button, I get a dialog to select what to share; but
when I make my selection, all I get is a spinner; other participants get
a blank screen from me.

Searched for: screen sharing with kde/plasma on wayland

Found this:

and this:
https://bbs.archlinux.org/viewtopic.php?id=269671

There's a test page:
https://mozilla.github.io/webrtc-landing/gum_test.html
but it's of little use for this issue; better one below.

After finding this:
https://wiki.archlinux.org/title/XDG_De ... l#Backends
I removed xdg-desktop-portal-gtk, rebooted and tried:
https://mozilla.github.io/webrtc-landin ... _demo.html
while I can affect the Canvas grid with the mouse, the Remote Video area
remains blank. On my Windows 11 laptop, the remote area displays the grid
in inverse video and tracks the changes on the Canvas.

Anyone else having this issue? Solution?

Thanks,
Pierre
