Inventory items/blocks blacks out.

I would have all the blocks and items from the Creative window appearing and they did.

But, when i opened the window i saw some items/blocks blacked out

Steps to Reproduce:
1. Open a new world in Large Biomes with Creative and Cheats On.
2. Simply start clearing a little bit of land.
3. Open your inventory and choose your blocks of desire.
4. See The Bug
