      The bug

      Flooded/underwater rooms get a ceiling of water as if reaching an air surface, even directly below a solid block.

      If the solid block is replaced with a waterlogged block the "water surface" effect is removed. But a solid block produces the water surface effect. This is intermittent, it does not effect all blocks in this way, however I have been unable to determine why, or find a work around this purely visual, but incredibly annoying bug for anyone building under water.

      I think it has something to do with proximity to glass, extending 1 block away.

      To reproduce

      1. Build this structure and fill it with water
      2. Go inside
        → On the edges of the room's ceiling, you'll see the water surface
      3. Break the middle block and replace it with glass
        → Now the water surface is visible everywhere

      It would be expected that the water ceiling only renders from above, but not from below.
