Not sure if you're the only one but I'm also using Fedora and everything is working perfectly on an up to date installation.

I had an issue where the desktop would take a fair amount of time to load, and I have a very different issue that I don’t even know how to categorise. There’s a wayland app in which keyboard works but some keyboard related things stop working if I lock my screen.

The app is a game (Victoria 3). Normally, space pauses / unpauses the game, escape opens the pause menu, etc. If I lock my screen, those things (and more) stop working, but the keyboard as a whole works. E.g. if I go to save the game I can input text in the save name text field. Keyboard and keyboard shortcuts as a whole still work everywhere else.

The problem goes away if I log out and log back in, but otherwise persists across game session (i.e. closing and reopening the game doesn’t fix it).

I've had an issue where I can't log in on my main screen
