Graphical error, showing invisible polygons in reflections

[gameboy1234]

I noticed a problem rendering trees in reflecting water.  There are "extra" polygons that don't look like they're supposed to display that show up in the water reflection.  It's not too noticeable in regular mode, but in cell shaded mode the extra saturation makes the polygons really stand out.

 

here's a pic:

I'm seeing these on both beta and live, so I think this is an issue with reflections in the experimental graphics rather than beta.
