I hope they do fix it. Yes, my Menu bar is red right now, and I have a pink / grey background today for some reason...often it is all sorts of pastel shades.

Mine is currently green, although it is often brown, and sometimes more orangey. It literally changes colours!

Glad it's on the fix list - been driving me nuts looking for a preference and trying themes.
