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
Build this structure and fill it with water
[media]Go inside
[media]
→ ❌ On the edges of the room's ceiling, you'll see the water surfaceBreak the middle block and replace it with glass
[media]
→ ❌ Now the water surface is visible everywhere
It would be expected that the water ceiling only renders from above, but not from below.

if you fill a villager house with water a put block in hole at top it creates two lines with glitch, one line without
I'm able to confirm this.
We have a ticket for the water surface being visible from above even if there are blocks above (MC-125546), but I don't think we have one for it being visible from underneath. At least I couldn't find any.
