Additional Context

No response

try /flywheel backend instancing and /flywheel backend batching and use which ever works best for you.

I'm seeing the same problem and did some more testing.

After trying both flywheel options, they both have their problems.

Batching seems to solve the visual bugs
However, it suffers from severe FPS drops with components like waterwheels.

Testing with just Create, Sodium and Indium installed, it goes from 400+ FPS without any waterwheels placed to 110 FPS when you place 6 of them.

This isn't a huge problem on its own, however on larger modpacks it becomes a HUGE performance issue.
On my personal pack, the same test goes from 90+ FPS to around 30 FPS with the same 6 waterwheels.

Instancing mode seems to be the opposite.
It completely solves the performance issues, but it creates the black chest tops and train tracks as seen on the OP images.
