For some reason when the game went live I have a rather large square on my monitor on the left side. I got the early release. I have a 4070ti 32gb of ram and a 13700k. no issues with gameplay other than a large square on my 32" G7 samsung monitor. the mouse cursor can still be seen when i hover over the square. its about 1"x1" so its essentially between the cursor and screen, on the left side, centered vertically. All new hardware and software. this is the only game that does this.

I also have this just on my laptop when using HDMI to my TV.
So the fix for this is in in Nvidia overlay.
hit alt-z goto settings, performance monitoring, and turn off show reflex flash indicator.
I had my overlay turned off, so I had to goto ge force experience, and turned it back on, just to disable it.
Hope that helps everyone out.

Works for me. Thx 
It work for me too. Tanks!
mine was already off but toggling it on shows a little black square on the left side of my monitor. that seems to be where the issue was starting from. must just be a random visual bug hasnt happened since i restarted computer tho. also opening the map seemed to temporarily clear the black square when it was occurring
