When breaking a block causes tiles to disappear, the chunk may sometimes decide to not remove deleted tiles from the model. The next model update fixes everything.
Steps to reproduce
Enter a world, start breaking grass blocks. At some point you will see floating grass tiles that should have been removed. Break another (unrelated) block and observe the tiles disappear. The issue seems to trigger randomly and quite rarely; perhaps once every twenty blocks or so.
This is probably related to lack of synchronization in ChunkRender.
