Incorrect Arrow Trajectory on 32:9 Monitor

[NightHawksix]

When I use SmoothCam with the trajectory line, my arrows are going way off (probably 3ft off when shooting from ~30ft away) to the right and up a bit. This is only when I run at 32:9 resolution.
To test, I reverted back to 16:9 and it shoots right on (maybe a little high, but still pretty accurate).
Please fix. I LOVE this mod, and I'm super bummed it doesn't work with my fancy new monitor.
