While using shaders, a box will replace your cursor... As well as when using a texture pack

Seems to be the case whilst having a sign in your hotbar as well, but when the sign is in your inventory, it is the regular cursor.

I am using the faithful resourcepack, but why is it "sign dependant"? that doesn't seem like a resource pack issue...
Even bug in my game.
