Steam overlay in non-Steam games/applications?
Not really sure where to ask, as I have no clue if this is an issue with my NixOS configuration, Steam, or Anki. I just got the new Steam Controller and would like to set it up for Anki (the spaced repetition flashcard app). I've added Anki as a non-Steam game with its launch target set as "/etc/profiles/per-user/elnu/bin/anki" and set up controller shortcuts. These work, but the Shift + Tab Steam overlay doesn't display, and I can't see any radial menus I've set up with the touchpads. I'm using i3wm.
Has anyone tried something like this?
