Windsurfer trails leaving permanent artifacts

[burningthumb]

The windsurfer trails are leaving permanent artifacts in the water. When the camera moves these artifact "smear" and over time the entire water effect is ruined.

I raised this issue over on the boat attack water repository as well. I should point out I'm using the rendergraph-u6 branch. I uploaded some images that show it to the other repo, but I have seen it happening on this project as well. Just look behind the windsurfers, its pretty obvious.

As I said on the other project, I know its the surfer trails because when I disable them, the artifacts are not there.
