After these last rounds of restarts and updates, no matter restarting the client in Enders or Vanilla I get some weird graphical problems.

I can't say why or what triggers it, but since yesterday this happens often. Sometimes moving or reloading the map tile fixes it. And sometimes it just makes another mesh explode.
