Steps to Reproduce

1. Start the game

4. Look in any direction
5. Preferably find a torch to look at
6. If lazy just pan camera around youll see it on most maps

Explanation

Lightning bug (or something) when using a 32:9 monitor with 5120x 1440 resolution, windowed fullscreen with 16:9 aspect ratio on. Its rather annoying happens on pretty much all maps both from skybox and torch or other light sources.

You can even see it on the start screen right now, on the screenshot you can see how the "fog" or whatever its suppose to be covers the blood moon from the center of the moon all the way to the left of the screen.

The issue occurs on both Steam and Xbox PC app for me
