World generating in stripped parts

Some of the big trees in the Jungle biome are invisible, with an sort of wierd stripe pattern. When you try to go through the invisible trees you get a little spazzy and it might be pretty annoying.

Edit: The tree pattern keeps going.

Edit2: (Edit again, sorry for doing this) This does also apply to blocks like tall grass, I'm not sure to what more. And the invisible blocks also gets revealed when they recieve an block update.
