In case it is related... I have never seen that but I have seen a bright green color in a line down the center of the new forest bush ground cover (the ones that are randomly placed and are bigger than the normal grasses) when at a distance in the dark and it goes away when I get close. This is without Vulkan and using an AMD GPU.
Ryzen 5 2400G, Radeon RX580, 32GB RAM, Samsung Evo 870 SSD, Windows 10
I haven't tried adjusting settings to fix the issue because unlike what is shown above, it is barely noticeable and I'm perfectly willing to leave it that way rather than reduce graphics to try and get rid of it.
Anyhow, just adding this info in case it's the same kind of thing and maybe helps point to the cause of the problem. I'll include my log just for comparison.
