Fullscreen Mode Failure

[f4c3m3l70r]

Hello, I'm new here and dont exactly know if this post belongs in here.
Im playing Minecraft 1.7.2 an have small artifacts between the textures,
so I grabbed latest nightly version of lwjgl to fix it but I was not able to play in fullscreen mode by pressing F11 anymore.
Is this a bug? Or is it minecraft related?
Thank you in advance
