Can share screen with OBS Studio, but not with Firefox nor Chromium

[ghost]

I can share the screen with OBS Studio, but not with Firefox nor Chromium. They share a completely black screen.

I went through the Hyprland screensharing wiki page, the gist by PowerBall253, andthe official troubleshooting guide.

All looks nice.

Except that the official troubleshooting guide says thatFirefox and Chromium point to Pipewire 0.2 while I have Pipewire 0.3. COuld this be it? They say I have to install a "Pipewire compat library", but I cannot find it in the Arch repos.

If it works with OBS Studio, I don't understand while it should notwork with Firefox or Chromium.

I have the NVIDIA proprietary drivers and yes, I'm starting Hyprland as the wiki tells me to start it in case of NVIDIA proprietary drivers, with all the environmental variables set.

verify foorefox is running in native wayland. For chroomoom, you also need to enable webrtc pipewire streaming (as well as launching in native wayland)

that was part of the links I posted. It does

as above

the guide says that pipewire 0.2 clients are incompatible with pipewire 0.3 servers and need a "compat" library whatever that is.

In the meantime I found this very related issue

then it seems like a pw issue :-/

No it doesn't. OBS is using pipewire too.

Read the issue that you linked, literally.

I will write to xdg-desktop-portal-wlr.

In the meantime, on the AUR there is a package called hyprland-nvidia-git, which contains a patch for screensharing on NVIDIA proprietary drivers.

Where does this patch come from?

Where is the discussion that lead to this patch?

I cannot find relevant issue about screensharing here.

Maybe the one who came up with the patch can help me.
