Recently, since about a week or two I think, the Steam overlay has entirely stopped working for me. The in-game fps counter isn't there, my steam controller does not go into the game's profile, and no overlay appears on shift+tab, and it also looks like maybe Steam's shader pre-caching isn't working, because I'm occasionally seeing "Compiling shaders..." in the bottom left corner with pretty much every game.

Has anyone else had this issue, or know how to debug this? Logs don't show anything odd.

I'm running Steam on Fedora Sway, with proprietary Nvidia drivers, and the games with gamemode, and gamescope.
