I found that after defeating the Ender Dragon on 14w31a, that the torches perched on the End Portal leading back to the overworld were glitched. Instead of being on the side of the bedrock, the torches were floating around the bedrock pillar in the center of the portal. Not a huge bug that causes the game to crash, just a graphical error, is what it seems to be.

Reproduce the glitch:
1- Go to the End
2- Defeat the Ender Dragon
3- After the portal has generated you will see the glitched torches.
