Can confirm this with backport 1:5.2.1~rc2-0ubuntu1~xenial0 and gtk2 backend.
Workaround: Use gtk3 backend, installing libreoffice-gtk3 should be enough (Please report back if that doesnt suffice, libreoffice should prefer gtk3 over gtk2 if both are installed). In case, gtk3 is installed but is ignored (which it shouldnt, please report), forcing LibreOffice to gtk3 with: SAL_USE_VCLPLUGIN=gtk3 libreoffice would be a workaround. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1619442 Title: An empty bar appeared above the toolbar after upgrade to version 5.2 (Unity7) Status in libreoffice package in Ubuntu: Confirmed Bug description: After upgrade of LibreOffice to version 5.2, an empty bar appeared between the toolbar and the window header. The empty bar contains only the button Close Document. If a new instance of LO window is opened from an existing LO window via Window -> New Window, the empty bar is absent in the new window and the UI looks correctly.
