Hello, ive used this amazing mod many times, and today ive desided on a new server that I will make my own armour skin, but when I started placing the blocks down they went green and glowed, and the textures mixed I could tell what was on top or bottom and made it very hard to keep building, but when I asked if this is a problem the whole server has no one else had experienced it, I'm questioning maybe its because I changed my settings because of the server lag, or a problem that's caused from anything else? Please get back to me as soon as possible

Do you have an AMD/ATI GPU?

Interesting I sometimes get this kind of glitch too. Then I reset my Video Setup (Optifine) and it's back to normal.

EDIT: Found. Setting "Chunk loading" to "Multi Core" causes the problem.

The cubes shift between white, light/dark green depending on the chunk you are in.
