Weird lighting glitch under bedrock layer (Bedrock)
It kinda looks like vibrant visuals (I don't have that on)
I guess there's a light source below the bedrock layer to light up the bedrock in Bedrock Edition. If you put a non-full block, like a bottom slab and then put a non-full block above that, like stairs, it creates this weird diagonal lighting effect.
