Version information

sodium-fabric-mc1.18.2-0.4.1+build.15

Expected Behavior

The surface of the water should appear completely straight, much like it does in this geometrically equivalent slab arrangement:

Or like it does when the arrangement is surrounded by full blocks:

Actual Behavior

The water level does not appear even, instead bulging in the center.

Reproduction Steps

1. Create an arrangement of four stairs as to create an "offset slab"
2. Waterlog these four stair blocks
3. Stare at the water

Additional information

Vanilla bug https://bugs.mojang.com/browse/MC-127270. It seems that 1.18.2 made this effect less intense, but it's still there.

This seems to arise because the water doesn't have any full blocks outside of it for it to appear at a higher level, despite it being contained by solid blocks in its own space.

(Split from #91 due to 1.18.2's changes)

Unlike #1212, which is wrong, this report is a valid request for a visual enhancement compared to Vanilla (which looks exactly the same as Sodium): in this instance, the water looks tilted, but is actually not flowing.
