MySite Theme Changes – newsfeed not picking that up!

Been having an issue with mysite themes in a demo rig I have configured.  Oddly the ribbon is showing no color, therefore the links to skydrive etc. are showing as white on white (took me a while to spot it was there at all).

Anyway – it is possible to re-theme the mysite by manually activating design gallery (I was logged in as administrator but you can change that to any mysite user name) via the following URL and pick a new theme

http://servername/mysitehost/personal/administrator/_layouts/15/designgallery.aspx

Got it I thought, silly me!

Whats odd is, that the newsfeed doesn’t adopt the changed theme, so I’m stuck with a partially working and mis-themed 2013 setup and I have no idea how it got broken to begin with.

One to file as a bug with Microsoft methinks!.
