Package: x2goclient
Version: 4.0.5.3

In two Debian stretch computer with all x2go versions -debian, x2go and
x2go nigtly- when try to open a menu in a GTK3 program, the menu dont
show. Usualy you get a thin line on top right corner with a width of
the menu. Also sometimes in the same position the line is a bit biger
and show one item of the menu. GTK2 menus work well.

Tested in diferent desktops, console...

Cheers, Jabier.
