System has 3 identical 1440p monitors (1,2,3). The left most monitor (1) is in portrait mode. Primary monitor (2) is the middle one in landscape.
This causes the game to launch on the primary monitor (2), but using the left most monitor(1) aspect ratio.
Switching between fullscreen and windows doesn't help.
Video resolutions are all in wrong aspect ratio, even though the correct aspect ratio is selected.
Game is only playable if I unplug the portait monitor.
