As for the screenshots you posted, the top one is 7680x1600 (3x 2560x1600) or 3x16:10 displays. It would appear that the hud is scaled based on 16:9 aspect ratios, if I crop the viewable area in the first screenshot at the menu then it is 2844x1600 which is a 16:9 aspect ratio.
Seems the game has a bug with eyefinity/surround resolutions using 16:10 displays.
Can confirm the stupid bezel correction 16:10 bug is happening to me too. :x Otherwise it's working perfectly. Quite annoying, I've been using the bezel correction toggle hotkey (set up in nVidia control panel) to toggle when necessary, I think it's CTRL+ALT+B by default.
I'll definitely give that chromatic aberration patcher a try later, thanks delphium!
