Package: gnome-shell
Version: 42.0-2
Severity: normal
X-Debbugs-Cc: [email-masked]

When trying to record a screencast, I got the following non-specific
error in the logs:

gnome-shell[787]: Error starting screencast

And the screencast didn't start recording.

I could reproduce this in Fedora 36 using pipewire 0.3.49. I cannot
reproduce anymore since using pipewire 0.3.50.

> reproduce anymore since using pipewire 0.3.50.

Is that the only thing that changed on your system? There was also a
recent fix in  xdg-desktop-portal 1.14.3.

Either way, Debian Unstable has both xdg-desktop-portal 1.14.3 and
pipewire 0.3.50 now.

Thanks,
Jeremy Bicha

In my case, I did not change the xdg-desktop-portal version.
