Using Blue3 or Blue3 Wide:
1. Play music - select several tracks, at least one with a long artist or title name
2. Open the "Now Playing" screen
3. If the text of the Next Song (artist or track name) is long, and scrolls, it displays white when it first appears and then turns to greyish when it scrolls.

h4. Additional Information
This issue occurs whenever a fadelabel control is used with a diffused textcolor (80ffffff) as in the above case of the Next Song on Now Playing. The fadelabel will always display the fully opaque color before applying the diffusion.

I believe there are only a few cases where fadelabels controls are used with diffused textcolors. One is with the scrolling text on media overlays when music or video is playing. However the diffusion is so slight the 'bug' is barely noticeable.
