I went on minecraft after my hard drive was replaced and was brand new and I am having a glitch where the screen freaks out and its very glitch. I show in the video below I did in my realms . I also dont know how to fix it and I would really like some help with it. I got everything from minecraft.net so it is the real game my user is 15posnern if that helps. It seems to happen when the chunks are being rendered. If you want I can skype and show you it. My skype is bridal maven so add me there. Also that was not it what you just said it was. Its all lighting and its not repeating and not at all the bug it was said to be. First picture is what the glitch sometimes looks like and the second is what the area normally looks like
