This is an issue with how vanilla 1.7.10 renders transparent objects. It happens even in vanilla if you're above clouds (which is when they become transparent).

CoreTweaks amplifies the issue by making the clouds always transparent, even when you're below them. This can be configured using the cloudHeightCheck config option: set it to anything other than ALWAYS_TRANSPARENT as a workaround.

Interestingly, the same issue doesn't happen in Beta 1.7.3 (where clouds are always transparent), which shows that the issue is fixable. I will look into whether I can make the 1.7.10 renderer work the same way.

Really interesting, thank you for the detailed response.
