I was on one of my worlds when I noticed some strange lines coming out of a building I had created. When I went inside, the paintings I had placed in the building were not in the right spot. They had shifted to the left, which caused one to be covering the door. The strange lines appeared to projecting off of the paintings. I tried removing the paintings and then replacing them, but I got the same result as before. I saw this same thing in several of my other buildings. I have taken 2 screenshots of the bug, using a wall to show what's going on. One is from 1.10 Pre-Release 1, the other is from the previous snapshot, which doesn't have the issue.
