Waterlogging a chest creates z-fighting water and chest textures on the bottom surface of the chest. Affects previous 1.14 and 1.13 versions, optifine and not, texture pack and not. Only affects where chest and water intersect. To reproduce, simply look at the bottom / look under a waterlogged chest. Vanilla minecraft
