Shot arrow hits the ground before player and then teleports to place a real impact.

The point is that when you shoot an arrow and falls before and after the character appears to be about 30 blocks away (see screenshots). When a critical hit even 60 blocks. It's quite a serious bug, but it could cause problems on some maps.
Here is a link to the video where it is shown in more detail:
