Searched the forums but ain't much help on SteamOS! Been testing my game for steam, windows,mac, ubuntu all work fine.
1.SteamOS when you start the game the default steam overlay with the gamepad pic causes the screen to be cut instead of going fullscreen, it shows the top left corner of the game only and the rest of the screen is black.
2.The game supports gamepad buttons but it locks those buttons in game use so at the steam overlay you cant change any selections.
Any ideas?
