Gnome 48 screen recording broken

Luxuride · September 17, 2025, 11:54pm

Hello,
After updating to NixOS 25.05 all screen recording and screen sharing on gnome is broken.
It creates single frame stream that doesnt change, and confuses video players.

In the meantime I will downgrade to NixOS 24.11 but if I am the only one experiencing this issue I’m willing to help with debug logs because I need this fixed for my work.

I’ve not seen anyone else mention this specifically, but the wayland migration (which I believe took full effect on GNOME with 25.05, but it’s been a while) changes how screensharing is handled. Wayland in general doesn’t just let random applications capture any screen content they want, in an effort to thwart malware (and I suppose proprietary software that acts like malware).

Instead, the software needs to request permission via the xdg desktop portal spec, so that you can click a button that says “yes I want this application to record my screen”.

Unfortunately, despite literally a decade of pre-warning, not all applications got the memo. Most notably, the chrome project just barely started supporting wayland about a year ago, and builds of electron (which is based on chrome) still generally don’t flip the experimental flag for wayland support.

Distros are finally starting to turn off X11, and NixOS is among the first to do so, because, y’know, relatively cutting edge distro. This means that people finally start noticing that the software they use is dragging its feet - most likely what’s happening to you here.

So, please tell us which software you’re using and how you’re using it. Share your configuration while you’re at it. Most likely you need to turn on a few settings to make screensharing work on wayland, and override a package setting or two.

9:1 you’re using some electron-based proprietary thing (teams?) that’s just poorly maintained by people who don’t actually give a crap about Linux desktop support.

If you’re using something more exotic, run it in the terminal and share the output, and/or the output of journalctl --user -f (started before you launch the broken application).

My configuration is Files · desktop · Luxuride / nixos-config · GitLab
Just 25.05 in flake.nix when I had the problem.

This is the result of journalctl --user -f after launching gnome screenshot tool for screen recording

I know what desktop portal is and don’t expect x11 screen recording to work.

and screen recording works normally

TLATER · September 18, 2025, 12:03pm

Awesome, that helps

Yep, those immediately stand out. Looks like a codec support issue of some kind; either whatever library ends up backing this doesn’t support the codec an application is asking for anymore or some kind of caching is getting in the way.

IIRC gstreamer has a directory in ~/.cache, you could try deleting that just as a first idea, I’ve seen that work before, but it’s a shot in the dark.

I would suspect my graphics driver using something like HDR, and pipewire not supporting that. A quick glance at pipewire issues doesn’t reveal anything. Do you get other results when attempting this with Firefox?

Luxuride · September 18, 2025, 3:27pm

Deleting ~/.cache didn’t solve the issue.

I have tried it with firefox, and same problem, but no pipewire error.
