[amdgpu] Screencast app crashes after recording is stopped

[Sergey Zolotarev]

Every time I try to record a screencast via the built-in feature triggered by Ctrl+Alft+Shift+R, it starts recording successfully but when I click the stop button, the recording stops and nothing is saved to ~/Videos/Screencasts. This happens with both Wayland and Xorg sessions.

Here are the relevant journal records:

That might be an amdgpu-specific issue. Sadly it doesn't seem common enough to show up in the top 100 gjs crashes for 22.04:

  https://errors.ubuntu.com/?release=Ubuntu%2022.04&package=gjs&period=month

It sounds like this bug though:

  https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/6747

which is fixed in mutter 45.1 and later.
