Weird letter-boxing occurring in FireTV games on 4:3
I'm utilizing a 4:3 monitor to test-develop on, and have had this weird bug crop up several times. I'll launch a game, and after the GameCircle indicator fades out the game will then have some weird ugly letterbox bars obfuscating a chunk of the screen. If I bring up the GameCircle overlay, the bars vanish temporarily until I close the overlay and return to the game. Here's a video of it occuring with Badland for FireTV.
