I pulled gnome-shell, gnome-shell-common, mutter, and mutter-common 42.5-0ubuntu1 on 22.04.1 LTS, rebooted, and was able to immediately reproduce the issue by locking my screen and attempting to unlock it.

[ Test Plan ] 1. Find a dual GPU system where both use open source drivers (like Intel + AMD). 2. Ideally also attach one monitor to each GPU. 3. Open Settings and repeatedly change the monitor layout pressing Apply each time. Expect: System does not crash. [ Where problems could occur ] Anywhere to do with screen updates since the entire triple buffering patch has been updated.
