Re: Color space problem - QCRenderer not rendering tranparency

I am creating a CIImage programatically from a GL texture using either
NULL as color space or CGColorSpaceCreateDeviceRGB().

This CIImage is set as input of a QCRenderer (published input), which
renders that image.

When I use NULL as color space, the rendered output preserves
transparency of input image. When I use the colorspace, the
transparent regions become opaque. I need the colorspace because
otherwise, colors are not OK (too light). Is there any problem in my
setup ? Or is it a bug ?

I don't think you should observe such a difference in rendering. Does it happen with a minimal composition like just a billboard?
