I've been using sway for more than an year but recently got an issue where all QT applications randomly close and can no longer start until I restart sway.
The screen sharing works fine with xdg-desktop-portal-wlr and with Fedora moving fully into pipewire I'd expect things to get even more stable under wayland.
One thing I'm missing is a decent screen recorder (gif/mp4). For screenshots one can use swappy, it works perfectly.
