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.
