1.19.3 fabric (quilt) using iris 1.5.2

as well the junctions of blocks (with connected textures), move in waves:

This happens because the CTM is using the translucent render layer, and is treated differently than opaque stuff. if the CTM render layer was cut-out it would work fine, but i know that has its own artistic problems.
you can see it through the water fog because the water fog when seen from outside the water is always rendered before the pass that puts transparent things in.
when you go underwater, a different water fog is rendered after the transparent pass, so it is always in front of transparent things.
i cannot do much about this issue without essentially restructuring the shader, which is a whole task in itself that i wont be doing.
