When using Optifine, the Mossy Limestone and Overgrown Limestone textures are semi-transparent, showing empty areas beneath them as outlines
(images attached, also seemed to highlight algae)

I assumed this was a shader issue, but I tested it with blocks from both vanilla mc and other mods, and did not run into this problem. Limestone bricks/slabs etc work fine; it's just the mossy and overgrown blocks that seem to do this. Did not get to test with other mossy/overgrown blocks, only have limestone at the moment.

Using Optifine 1.16.5
shader in the screenshots is ComplementaryShaders v4.1, but also tried BSL v8.0.01 and had the exact same issue, so I'm guessing it's an issue between Create and Optifine.

Also tried turning on Compatibility Mode, to no effect.

Any tips for settings I might be able to change would be appreciated.
