Off center/broken crosshair

Specially noticeable w/ the crowbar and revolver, but every crosshair seems to be a little bigger from the left side (like by 1 or 2 pixels but it’s there)

I have a 1440x900 monitor which i believe is the reason of this, changing res and aspect ratio doesn’t do anything.

Same happened to me, but I have a 1920x1080 monitor.
