THIS BUG IS FIXED IN 21w10a
The fog is not rendering in a smooth circle on AMD cards and integrated graphics even tough is supposed to be solved (the fancy option isn't available).
This feature is working correctly only on Nvidia graphics cards.

Update: Sodium, a mod made by jellysquid_ fixes this issue. Fog is rendered properly when using this mod on AMD graphics cards and integrated graphics.

OpenGL: Intel(R) HD Graphics 4600 GL version 4.3.0 - Build 10.18.14.4170, Intel
Outdated Intel drivers, update to V15.xxx: https://downloadcenter.intel.com/download/25489/Intel-Graphics-Driver-for-Windows-10-15-40-4th-Gen-
OpenGL: GeForce GTX 860M/PCIe/SSE2 GL version 4.5.0 NVIDIA 358.91, NVIDIA Corporation
This is one version behind (new drivers released two days ago)
Please update your cards to current drivers and retry.
Updated both to latest - no change visually. The only difference I can see between the cards is Intel's GL version 4.3.0 vs NVIDIA's GL version 4.5.0 but I have no idea what difference that would make if any.

Ok, it was worth a try.
Can confirm this is happening in 1.10.2. Fancy fog uses a function only available on NVIDIA drivers.
Affects 1.13 and 1.13.1.
In 1999 Nvidia created a standard known as "nVidia Distance Fog" which is only compatible with their cards. When using a Nvidia GPU this gets enabled by default but isn't supported on AMD and Intel GPUs. You can disable it in OptiFine by setting "Fog" to Fast.

Yes, that's what I am saying it's working as intended on Nvidia Graphics cards.

Yes, it is in fact fixed! Really glad to see this bug fixed!
