I have installed R14 direct from the Ubuntu live CD - overall it seems very stable compared with earlier versions, no crash boxes at all!!!
 
Everything seems to work very well except for the UI for Libreoffice
On the live version the UI looks as it should picking up the KDE settings for fonts etc.
Once installed the LO interface drops back to what looks like a very basic GTK2, small fonts and grey background
My guess is that this is Raleigh but I cannot be sure.
 
This also happens if R14 is installed over command line base install of Ubuntu so it does not seem related to the live media as such.
 
I don't know if LO is controlled by GTK2 or GTK3. In the past I would just install the relevant Gnome, GTK or KDE integration package and all would be well.
However, if I install libreoffice-gtk or libreoffice-gnome the font/UI problem is fixed but all the icons vanish after appearing briefly.
 
This seems to be the same issue as identified back in 2012 with the gtk-qt engine.
Behaviour is as described here.

The bit I do not understand is that it looks fine on the live media, so it must be possible for it to work as expected. Presumably there is some kind of path error somewhere so that the installed version cannot see the correct files.
 
Does it make any difference that the GTK-3 setings show that the gtk3-tqt engine is not installed when it is??
 
I know it seems a small point but it is driving me nuts as R14 is just so much quicker and nicer to use than MATE, Xfce etc. so any help or clues would be very welcome.
