This here is with an RX 580. Do you observe a modeline switch when starting or minimizing the game, i.e. display turns black for a short moment? This happens here with mainline wine and most games when exclusive fullscreen mode is selected in the game. Though there is only one display with one modeline available via xrandr, making that switch attempt even more pointless.
