unable to use screencast when running niri for first time

[JimitSoni18]

System Information

void linux on thinkpad, glibc

• niri version: 0.1.7

• Distro: void linux, glibc

• GPU: intel integrated

• CPU: i5 4200M

i have observed that when i run niri in a dbus session, using dbus-run-session niri --session, then start a browser and try screensharing, in google meet or discord or anywhere else, the gtk window picker does not open. here is an image after i left the google meeting saying it could not share screen:

however, if i exit niri (pressing super+shift+e) then run command niri (not running in a session, and not using flag --session), then exit that again (pressing super+shift+e), and run niri in a dbus session again, using dbus-run-session niri --session, the screen casting starts working, and the gtk window picker appears this time. see the picture attached:

here are some spawn commands i run when i run niri, if it helps: spawn-at-startup "pipewire" spawn-at-startup "dunst" spawn-at-startup "swww-daemon" spawn-at-startup "swww img wallpapers.webp" spawn-at-startup "eww" "open" "bar"

i thought that maybe niri requires pipewire running on startup to cast screen, so i tried pipewire before starting niri, but it did not work.

You currently need to run pipewire before niri, spawn-at-startup is too late for that.

i tried pipewire before starting niri, but it did not work

That's weird, it should work I think.

yeah i'll try again and see if it works

now i am able to use screencast, previously i was spawning pipewire directly in the shell using nohup pipewire > /dev/null &, now i an launching in a fish script, and it does seem to work.

i still think it is weird that it does not work when pipewire is spawned from the shell
