Find your XComEngine.ini file under C:\Users\%username%\Documents\My Games\XCOM2\XComGame\Config
Then find:
[Engine.LocalPlayer] AspectRatioAxisConstraint=AspectRatio_MaintainXFOV
Change that with this:
AspectRatioAxisConstraint=AspectRatio_MaintainYFOV
That fix's most of the 21:9 issues.

It seems the ini files are inherited from XCOM:EU/EW but support is quite different this time around and some settings are either inactive or better left alone. DefaultAspectRatio and ConstrainAspect for example are useless, unless you really want to add black bars to the picture !
