McNeel,
the black parts of text dots are transparent when making a screenshot with ViewCaptureToFile and checking the Transparent background option. I was saving to a .png and using a self defined Display Mode.

Sorry there have been no responses. It actually looks like the Text of a dot is transparent. This looks like a bug.
