Dynamic water changes team colors

[xyz]

Hello,
I've noticed something really strange on a BA game on a map with water set to dynamic. Amphibious units change their team color when they enter the water (see screenshots). If i turn the water rendering to anything else then dynamic the color returns to normal.

Setup:
Win XP sp3, AMD X2 5000+, 2Gb ram, NVidia GForce 9800 GT 512Mb.

Infolog and spring conf are in the zip file.

This is the commander just about to get out of the water.
