GNOME screen recorder drops vast majority of frames

[Matthew D. Mower]

When I try to record a region on my screen, after about 4 seconds the frames stop updating. In the attached video, I am toggling between the two visible windows every half second, roughly. The only frame updates after 0:04 occur at 0:33, 1:07, and 1:40.

Additional testing:
- My laptop (also with AMD graphics, Lenovo T14s Gen2) running the same OS also exhibits this issue.
- Switching my session from wayland to XOrg does not remedy the problem.
- Installing AMD drivers from https://www.amd.com/en/support/linux-drivers does not remedy the problem.

I believe this is the same issue as reported here: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/5585

It looks like the fix for this was just prepared for jammy-proposed a couple of days ago: https://git.launchpad.net/ubuntu/+source/gnome-shell/commit/js/dbusServices/screencast/screencastService.js?h=applied/ubuntu/jammy-proposed&id=40715f8dfa77b9edd5a8fad033718df4d4d65440

I've tested this change locally and verified it resolves the issue:
1. $ mkdir -p ~/.gnome-shell-custom-overlays/Screencast
2. $ gresource extract /usr/share/gnome-shell/org.gnome.Shell.Screencast.src.gresource /org/gnome/Shell/Screencast/js/screencastService.js > ~/.gnome-shell-custom-overlays/Screencast/screencastService.js
3. Apply changes to screencastService.js from https://gitlab.gnome.org/GNOME/gnome-shell/-/commit/d32c03488fcf6cdb0ca2e99b0ed6ade078460deb )
4. Add the following to ~/.profile: export G_RESOURCE_OVERLAYS="/org/gnome/Shell/Screencast/js/screencastService.js=$HOME/.gnome-shell-custom-overlays/Screencast/screencastService.js"
5. Logout and login

That's the fix for bug 1987631 so we can merge with that.
