Hi,
I know that the posting that you have made is now some what old but wondered if you got to the bottom of your problem? Since upgrading to 1.01 I have been having the same issue. My hardware wfm scopes show a shift in all rgb channels as well as luminance and my vector scope shows a heavy increase in magenta. The problem exists only within color and once the rendered image is sent back to FCP everything is displayed correctly. Quite bizarre considering FCP and color are using the same 10 bit codec.
I too am using kona 3. I have done all the usual: reinstalled drivers, resat the kona 3 card and still no joy.
Did you find a fix or workaround at all?
