  2. Summon a one block tall space of stone blocks with some light inside by using the commands provided below.

    /fill ~1 ~ ~1 ~15 ~2 ~15 minecraft:stone hollow
    /setblock ~8 ~1 ~8 minecraft:light
  3. Switch to spectator mode and look at the lighting toward the east side of the one block tall space.

Observed Behavior:

Smooth lighting renders incorrectly thus creating harsh transition between light levels.

Expected Behavior:

A screenshot is not a valid replacement for the rest of the report.

Provide steps to reproduce, expected behavior and actual behavior, or this will be closed as incomplete.

The issue here isn't the 15-14 transition, as this occurs at the end of the tunnel regardless of the light level.
