What is LWJGL?
LWJGL is the LightWeight Java Game Library. Essentially, it is what Minecraft uses for graphics, sound, and input. The latest version of LWJGL is 2.9.0.
 Why update?
- Updating will fix some input bugs where keys seem to get stuck if you click at the same time. It also removes the "ghost" mouse pointer clicking.
- Some users report a performance increase upon updating.
- This can also potentially fix some issues regarding sound not working/cutting out.
- It has been reported to fix intermittent crashes on Windows.
- It has also been known to resolve the "cannot get JAWT interface" error for Mac users using Java 7.
 Where to download
Select the latest stable release and download the lwjgl-X.X.X.zip. You should also backup your .minecraft folder before following the steps below. As a last resort, you can use the Minecraft Launcher's Force Update option to reset the files.
- With 2.8.1, on most 64 bit computers, the lwjgl64.dll update will cause a black screen crash. You can revert to the backup version you have saved if needed.
- Again on several 64 bit computers, the OpenAL64.dll update can cause a sound glitch that makes bursting sounds. Keep a backup in case you need to rollback.
- Version 2.8.5 generally breaks shift-clicking; 2.8.4 and 2.9.0 do not. You can change the url in your browser to access 2.8.4 or 2.9.0 rather than 2.8.5.
- LWJGL 2.8.5 has a bug which sends a false signal that the user released all currently pressed keyboard keys when a mouse button is pressed. That means that your building will be significantly slower. Do not update to this version if this bothers you.
- This bug seems to be fixed when playing in fullscreen mode (Default F11), or updating to LWJGL 2.9.0.
 What to replace
In the lwjgl-X.X.X.zip, there should be two folders, named jar and natives. You should replace the files in .minecraft/bin and .minecraft/bin/natives with the versions from the .zip.
The .minecraft folder's location varies by operating system.
