I just made a simple Unity applet testing the water prefab and noticed a rendering problem when I run it as an OSX Widget. Attached are two images. The first (good.jpg) is the applet running as an OSX stand-alone. Here, you can see the scene geometry reflected properly in the water. The second image (bad.jpg) shows the same applet running as a Widget. Here, you can see that the reflection is rendering incorrectly.
