Ubuntu – LibreOffice blank menu bar after launch until reload LibreOffice GUI

libreofficemenumenu barunity

After launch LibreOffice (5.2.1.2) there is a blank menu bar which acts like normal menu bar, but looks a little buggy. After any reload of running LibreOffice it causes that this bar disappear, like I want it after start the program. This reload can be caused by change some settings in "Tools -> Options…" or "File -> Reload" or even when I run only LibreOffice at first and then launch Writer or something other. Screenshots will help.

LO1, LO2

Launched LibreOffice. When I click on this blank bar, It reacts like normal menu bar.

LO3, LO4

LibreOffice was opened like in many cases – open file of associated type (omitting LibreOffice welcome screen). Now there is blank menu bar as well. But when I click on "File -> Reload" this bar disappears.

Question:

Is it bug of LibreOffice or could it be something wrong from my side? If so, how to solve it? If not, is there any way to reload UI or something that can cause remove this bar, after start of any LibreOffice program? (libreoffice, libreoffice –writer, …)

PS: Theme, icons and mouse cursor doesn't have any effect on this.

Additional info: Ubuntu 14.04.5 LTS, Linux 3.13

Best Answer

LibreOffice 5.2 uses the newer LibreOffice-GTK2, so you’ll need to manually remove the old version before LibreOffice can be upgraded. Try

sudo apt remove libreoffice-gtk
sudo apt install libreoffice-gtk2 libreoffice-gnome

and check out if this helps.

I didn't try it myself, I still use LO 5.1.2.4 from Ubuntu-repositories.
