White borders in LibreOffice 5

[veluria]

Now that LibreOffice uses Gtk3, it draws some white borders around all of its toolbars. I'm not sure if there is anything that can be done about this or if they are hardcoded or something.

What's nice is that the issue with the white text in the menubar is gone, for example.

After some investigation I found out that the menu background color is used for the white borders. I.e. setting

.menu, .popup {
  background-color: red;
}

makes those borders red. That is clearly a bug in libreoffice, but given that the gtk3 support is still incomplete this will probably get fixed.

Thanks for your response. :-) I'll be closing this, then.
