I am trying to make this nice resource pack work with the latest Fabulously Optimized modpack, but this is the overall maximum I can get, and it's strange that these glitches continue to appear.

On top of the modpack, there are a couple datapacks on the server from vanillatweaks (nothing graphical related to ores though) and a resource pack from vanillatweaks again (only things on my mind that could modify the ores are the uniform ores and the alternate block destruction). Added mods I have: do a barrel roll, better f3, fabric api, and I'm pretty sure everything else is just from the modpack.
I'm sorry if the issue is not well filed, I will update with more information if needed.

It seems fixed on Embeddium.
Try to test it.

Because of this.
