The built-in screen recorder used to be solid! But at some point over the last few months it's become really unreliable; I don't know what changed.
I'm on Wayland, which is singularly responsible for most of my Ubuntu woes, but it did previously work. Which was amazing because pretty much every other screenshot/screencapture app has given up on wayland.
Two things seem to be noticably weird:
no errors; video is recorded and saved apparently fine, yet when I play one back motion only shows for the first second or so, after that it's just a static image for the duration of the recording.
Note: I have tried all the solutions from Screen recorder not working on Ubuntu 22.04 which is also reporting problems with this part of ubuntu 22.04, though the symptoms are different. Specifically I have tried:
sudo apt reinstall gstreamer1.0-pipewire
rm ~/.cache/gstreamer-1.0 xdg-desktop-portal-gnome is already installed.
grep -i screencast /var/log/syslog returns only pairs of lines like "Activating..." and "Successfully activated".
EDIT: I have tried 22.10, and it appears it works on that, but I'd rather stay on LTS if possible.
