No, it is fixed in a sepcific version of LWJGL, mojang just needs to add it to the launcher.
Please update the affected versions. Also, lwjgl blocks the use of some keys using an alternate keyboard layout.
Still affects 1.7.10 & 14w26c, but the glitch is now rarely triggered by the player. Updated steps to reproduce.
This is definetely not the result of a bad computer. In 15 chunks it loads instantly, and I have 300+ fps. But when I set it to more, restart the game and join the world, it doesn't load the chunks.
