It seems the lava world has a texture bug on one side. Especially visible on high resolution while changing the light direction.
Unfortunately this is one of those things I can't seem to replicate. It's probably an issue with how the shader is executed on certain GPUs.
Thanks for the report, I'm not sure that I'll be able to fix that but it's good to know.
