Menu layout bug in Linux Mint 18.2 MATE

Hi just install the latest libreoffice 5.4.1 using ppa from ppa:libreoffice/ppa

There is this layout bug not sure what cause it

all the drop down button ( in this picture is at font selection, font size and cell selection ) is too huge too wide.

I use Mint default theme, so it shouldn't be cause by this

Old version works normally.
