I just proposed a branch to screenshot that changes the workflow significantly. I’d love testing and feedback: https://github.com/elementary/screenshot/pull/253
You can download a flatpak bundle to test from the workflow page here: https://github.com/elementary/screenshot/actions/runs/3588339653
Publishing new GNOME 43 flatpaks soon. Web 43 is available. Evince and File Roller are being built currently 🎉
