Comment 8 for bug 966448

Unduped from bug 941066.
Reason:
- the issue hasn't be seen here before 5.8
- disagree with 'Desired resolution'

It is not desired to have a black aka tinted dash.
Expected is an option to disable the mourning dress.

IIRC there was the ability of dash to blur the background colour which disappeared, maybe it could be considered as a compromise option if transparency isn't desired by design.
