Recently when streaming games to my Nvidia Shield from my Windows PC the pictured on-screen keyboard has started popping up. It constantly tries to steal focus from the controller, affecting the game to think I suddenly have switched from a controller to a keyboard. Problem is, I have no idea which application is launching the soft keyboard. To make matters worse, I can't interact it with if I try to from my PC (using the keyboard / mouse).
Does anyone recognize this wonderful keyboard application?
