Line artifacts on water shader when not in DX11 mode.

Might be some kind of depth issue. It reminds me of the way depth textures are sometimes visualized with multiple lines, perhaps the water shader handles certain depth values incorrectly.

It seems to be hardware dependent, because it's not visible when using the (AMD) HD5770.

Version a3 of Surface Waves will have a tool for displaying the camera's depth texture so that users can show what the depth texture looks like relatively easily.
