I’m running Libreoffice on 64bit Linux Mint 17.1 Rebecca (Ubuntu Cinnamon), but for some reason LibreOffice is using an old, very very ugly, window manager - not Mutter (Muffin). It makes LO quite frustrating to use, so I’d really appreciate any advice! All other programs run the nice Mint GTK+ theme, but not LO. This affects all LO applications, Calc, writer, etc.
I have installed one plugin - Zotero, which may have been the cause of this problem. Uninstalling doesn’t seem to help.
Thanks in advance for any help!
