Today I was watching a video from panda about his enderdragon xp farm and I decided I wanted to see if it still worked in the latest snapshot. I went into the end and effected myself with strength lv.255 and killed the dragon tp'd out and back in it worked, then I just let the dragon die. After he died I was going around the end and I saw a weird shape to the left side of the screen(this: )
it seems to come and go as I fly around in one specific area(it has about a circular radius of about 75 blocks in which I can see it).
Anyway I didn't know what to think of it so I decided to ask the community.
The Meaning of Life, the Universe, and Everything.
Oh I know this, it is a very old bug. It is been in game ever since 1.9 beta pre-release 6. This is caused by end portal block because if you look carefully at its shape, you will noticed it is same with end portal. If you destroy end portal in creative, you will noticed that the weird graphic bug will gone. Perhaps you should report this to Mojang so that they will fix this in future update.
