All the icons still visible when in Superflat world type preset selection menu. (GUI rendering error net.minecraft.client.gui.GuiCreateFlatWorld.java is where the source of the problem is). For anyone who might not know what icons I am talking about are is the images of blocks that was showing in the version of MineCraft I was playing: 14w34b. There were blocks by each selection (I.E: Redstone ready, Bottomless Pit.) although these icons (I.E Redstone dust for Redstone ready, Feather for Bottomless Pit) were larger and the preset names were not present. I have not noticed then since.
