Thanks. I tried this, unfortunately if I disable the overlay the controller doesn't seem to be detected by the game, it launches in keyboard/mouse mode and the controller doesn't do much but emulate a mouse. Not sure if it's Steam updates but the overlay keyboard seems responsive now, but it still won't actually let me input anything. Clicking letters causes the autosuggest bar to show some options, but no matter whether clicking keys or one of the suggested words, they just disappear and don't make their way back to the game.
