Textures

The bug is the following: When I played in the last snapshot released (13w42b) everything was normal, then I went to play in version 1.6.4 and all textures were buggy, do not know if it's because of snapshot not downloaded properly or textures it is because of my internet, even though she was fast, but given a bug when I download the textures of the two versions, the resources are not lowered, apedar that the snapshot was displayed correctly, but in version 1.6.4 there. This bug also affects Texture Packs, which continues with the textures buggy, I sent some pictures for you to see the problem better. mend this bug, please :/
