I dont really understand what you are getting at with the water
but there is some very ugly looking patterning in the paving stones in the first picture!
I found something (a bit) similar when my M8 was new. It would generate ugly patterns in a specific shade of orange, as it approached over exposure:

I took the camera to Solms, with prints of these pictures, and they change the main board, seems to have fixed it
