I tried this mod and its pretty cool but I found the problem with the green sides coming out. It conflicts with AO. If AO OFF, it goes away. If AO is ON, green bleeding occurs. You can test it also with this texture mod with some PBR:

Mirror shader + above HD texture mod + AO ON - can clearly see the light texture mirrored but green bleeding and water PBR not working:
Mirror shader + above HD texture mod + GZDLiquidsPack mod + AO ON - can clearly see the light texture reflected from PRB but not mirror or green bleeding:
Edit - NO AA or FXAA was used.
