Fraps captures Firefox with incorrect colours in Direct3D 10 mode, e.g. blue is captured as orange. In Direct3D 9 mode, it captures the window correctly.

Thinking that this is a Fraps bug, I reported this to the Fraps developers first, but according to them, this is a bug in Firefox and IE9 (using a non-standard DirectX mode).

Thanks for getting in touch, and I apologize for the delayed response.  We have recently become aware of Fraps detecting several new beta applications that have been designed to use DirectX to display to the screen.  Fraps has been designed to automatically detect any application that uses either DirectX or OpenGL to display to the screen.  From your description it sounds like this application is using a non-standard DirectX mode that is designed to use a non-standard color space, this would explain the incorrect colors.

That's a RGB swap in the colors; it's capturing the color channels incorrectly (treating them as RGB instead of BGR).  I'm not sure what they mean by "non-standard color space" -- we're using B8G8R8A8_UNORM which is a perfectly standard and valid format, see http://msdn.microsoft.com/en-us/library/cc627090%28VS.85%29.aspx .  So I think this goes back as a Fraps bug.
