GUI and blocks turn white/one-coloured when changing mipmap levels

This happens to me if I enable mipmap when it is disabled, but not when I disable it or I change his level when it's enabled. It happens in different ways, sometimes affects the menu, the world and the inventory, other times only the world and inventory.

Graphics card: GeForce GT 430.

I'm having this problem to this only seems to happen if i change the mipmap setting by more then 2 and if you exit the menu and your in a world the game will freeze for a little bit then it fixes itself.

confirmed for the blocks. But i only have it when enabling mipmaps, THEN going back (ESC) to the game and it updates (short lag) to Mipmaps. Then it changes back to normal after the lag.
