Okay, thank you so much. All fixed.

and here in vanilla no optifine but with fog on and harder to see

this ss was from my server but i can go to single player and it will be the same

I have Nvidia card and even after setting rendering settings to 'Balanced' instead of 'Performance Optimized' didn't work.

But if this is intended, why would it only happen in River Biome? Same setup worked fine in all other biomes.
