When playing on MC 1.12 with Optifine I have issues with "Connected Grass Textures" and "Round Logs" which cause these invisible textures to pop everywhere.
Extremely noticeable on mountains.

I have same issue on 1.11.2 using Better Foliage 2.1.6. I did not experience this with the previous version.

Me too. T-T

Go to options -> video settings-> quality and change mipmap levels:1 to levels:4.
It's working for me :)

Derp :)

Fixed in 2.1.7
