Why would a game/app added as a non-Steam game open in its own window instead of within Steam with overlay?
I want to play my Xbox 360 games on my TV using Steam Remote Play, so I installed Steam, added Xenia as a non-Steam game. All settings look fine, but when I open the app on my laptop (the one they are both installed on), it opens in its own window, like it's just a shortcut to the app, rather than with the Steam overlay.
I would like to cast the games to my TV and take advantage of the controller mappings, but I'm sure the app isn't supposed to behave this way. Any ideas?
