Put the summary of the bug you're having here:
I can see the sky when exploring in caves.
What I expected to happen was...:
I should see a wall.
What actually happened was...:
I'm seeing the sky
Steps to Reproduce:
Randomly when exploring underground, it doesn't happen everywhere, but only in determined areas (like the one in the screenshot) it doesn't happen before or even if i go deeper, only that single wall disappears when i move far away, if i move closer it reappears.
I tried chaning the chunk distance/other settings/disabling shaders and recource packs.
