Screen sharing in Slack under Wayland

I can not get screen sharing to work properly with Slack while using Wayland. I tried editing the slack.desktop file to append --enable-features=WebRTCPipeWireCapturer, but it didn't help. Did anyone get it to work? I am using https://aur.archlinux.org/packages/slack-desktop. Screen sharing works for (some) single windows. I can share goland windows for example but not firefox. I can also not share entire screens.

Because slack will be running on xwayland. Assuming it has a new enough electron baseline get it to run on wayland: https://wiki.archlinux.org/title/Wayland#Electron

Re: Screen sharing in Slack under Wayland

I have set slack to run under wayland (and confirmed using xeyes) and I can still only share certain windows but not others (e.g. Firefox) and not the whole screen.

Re: Screen sharing in Slack under Wayland

I'm sorry for my very slow responses, this is my work machine and I was off sick for a while. xdg-desktop-portal and xdg-desktop-portal-gnome are installed and the systemd service is "active (running)". I don't know if the sway stuff applies to me as I am using gnome which afaik doesn't use sway as a compositor but mutter? I really don't have a deep understanding of compositors so correct me if I am wrong.

The two variables mentioned in the troubleshooting section are set as follows:

WAYLAND_DISPLAY=wayland-0
XDG_CURRENT_DESKTOP=GNOME

Re: Screen sharing in Slack under Wayland

You could try the patched version of slack: https://aur.archlinux.org/packages/slac … op-wayland (slack-electron should be patched as well if you prefer to run it with system electron)
Explanation for the changes: https://github.com/flathub/com.slack.Sl … 1807073763
The same is also discussed in the comments of the slack-desktop AUR package.
