Whilst playing 1.7.2, when I switch to Creative to use the Scroll-click to quick select a block, the entirety of the world turns black. It stays like this until I had changed Mip-Map levels to 0 then returned to the world. (Exited options menus)

Here is an example: http://gyazo.com/de1d83bb56772ba7fe21bdb16727db0d
It has happened multiple times throughout 1.7.2, yet I have never experienced it before on previous versions.
