I don’t know if this is how it was intended but it just looks weird so was just checking if the Bada**'s Predator head is supposed to be chopped off or not. I’m playing at 3440x1440 on PC.
Predator's Head Chopped Off in Customization Screen
Looks like a DPI scaling issue (i.e. you have your screen scaling to 125% or more). I do the same (using my PC in a TV-like setup, and this issue happens with some titles). Probably the easiest way to fix it is to find the .exe, right click on it, and allow the program to override DPI scaling under the Customise tab.
