Tried reloading, relogging, refreshing the chunks, refreshing the textures, everything and they will not go away. Im likeing an album of all the screenshots i took http://imgur.com/a/GvhVL
Have you already tried this without a texture pack and/or optifine (I think it's either one of those or both)? Because that might give you a clue what might be causing all this.
I don't have optifine and yeah I've literally tried everything it seems to be happening once a day round the same time. but I know that has nothing to do with it.
Try making a new profile (launcher)in another directory, and see if that solves it. Just do not copy anything to the new dir. Also see if your graphics card's drivers need updates.
Looks like a low memory problem to me. Though that doesn't explain why it happens at around the same time every day.
