Some strange images shows on the water when I put doors or other things in the water.
However, when I changed the direction of the door, the strange image disappeared.
If you put blocks like following pictures, you can see that.
If it doesn't work, try rotating them.
The symbol made up with emerald blocks in the picture tells direction.
Thank you for your report!
