The issue appears to be Optifine settings that are turned up to high so if use a version that isn't so graphics intensive the will show up. However, the picture that you are showing, while it does include the tree, it is also missing other areas as well, and is generally the result of lag because of a combination of settings, optifine and my computer.. I have this happen quite a bit.
