So, this is a very rudimentary fix to a problem that only like 2 people seem to have.
With Cathedral Landscapes installed, when you look at the world map at certain angles, and especially near Whiterun (for some reason), the water will disappear, creating a flickering effect when you try to move the camera around.
Note that you DON'T need this if you don't know what i'm talking about.

As it was pointed out by JonnyWang himself... a while ago, actually, the issue lies in custom terrain lod meshes that come with the Cathedral Landscapes archive.
Unpacking the .bsa and deleting problematic meshes is one way to fix it, but it's not a great solution when you have to do it every time you reinstall, plus it breaks compatibility with "A Quality World Map" mod.
This "fix" is just vanilla lod meshes (that are of worse quality but don't have the issue) but in the form of loose files so they would overwrite any .bsa automatically.

It does not break the grass/texture transition and it is compatible with AQWM.
