Black line on Local Height Fog [psx style game]

Hi, I’m having this problem, when local height fog is placed and player looks at the right angle black line appears across the screen. I making psx style game so i turned off some rendering settings (f.e aliasing) to make it look more authentic to retro games, so maybe problem lays there but I tried some things and don’t know what it could be. What I know about the problem:

-Black line disappears when looking any other angle
-TAA, TSR aliasing fixes the problem but it makes everything blurry, and i really dont like the look of it (other aliasing methods dont fix it [FAA, MSAA]
-Bloom extends the line
-With Fog mode set to Local Sphere Fog line disappears, but again i dont like the look of it so i will use it as a last resort

Do you have any ideas how to solve this? Thanks in advance.

Without bloom

With bloom

Line disappears when looking other angle (slighty down)
