Not sure what can be done here, but for blocks that have a face on them like Destructors/Constructors, Importers/Exporters, etc. The rendering is all messed up, seems like it's trying to render both layers?

it's just zfighting, add it to the zfighting whitelist

Cables do it too when passing out of a facade.

As well as External Storage.

ehhh it's an issue in every video game. i can't do much aside from the config option

I figured, I was just letting you know what else to put on the white list.

I added them to the config manually, and the destructors facing north and west still have issues. South and East facing destructors work fine.

Edit: It appears that any North or West facing refined storage block has this issue.

I also had add a wild card to all refined storage entries to cover the colored versions (e.g. "refinedstorage:*cable", "refinedstorage:*importer").

hmm
