[MC-58943] Leaves rendering incorrectly on 'Fast'.

On fast rendering, leaves about a chunk away render like they're on Fancy, while nearby leaves have a weird blackness in the texture.

Environment

Windows 7, Java 7

An example.

Works as intended, fast's supposed to decrease lag, and it lags less this way.

Wouldn't it decrease more lag when doing it the other way around since there are usually more leaves in the distance than near you?

Or is the same as with when riding minecarts: You see this line on which rendering appears to change (less accurate)...
