Pretty sure I didn't modify HudShift config between settings and I was using manual configuration instead of automatic (HUD would have moved to the edges otherwise).

Weird. I could swear I saw some people having problems with stretched game windows. Like, their screenshots showed everything stretched horizontally. But I guess it works.
