Leaves Screw up in "fast graphics" mode.

My graphics were set to fast because my computer sucks. What I expected was leaves to be normal and filled in. What actually happened is they were not filled in but had the fancy type holes in them but were filled with a strange sky color.

If there is any chat open or any chat that has not faded the leaves are filled with a black color that is not the natural block color.

To reproduce:

1. Log in
2. Choose world
3. Look at a tree in fast graphics mode.
