> This is actually a bug in the GTK3 implementation of LibreOffice. Well, rather its a fault of theme creators to ignore libreoffice-gtk3 despite it being around and shipped for testing since at least Ubuntu 12.04 -- exactly to bring it up to speed. The rushing to fix things now is entirely self-inflicted (same goes for me fixing the Ubuntu themes only this late, then again someone else could have at least given that a try too).
