Only on Mac OSX: Rendering/shader error within webplayer

Hi,

i have a problem when running my scene on web server. When i open my unity scene embedded into a html page on a mac, there are visualization problems. The 3D rendering looks awful and it seems that only some shaders are broken or rather the materials are very bright. GUI text labels are unsharp. If i watch the scene in fullscreen mode, it looks perfect - no errors. This bug exists only on mac computers. When testing the same scene on a Windows machine, there are now problems. When i test the scene on a mac and open the HTML page locally from hard disk rather than from web server, there are no problems, too.

Maybe someone could give some hints on that... Thanks for your time. yosh
