Quick FYI - downgrading gtk3 to 3.20.9-1 fixed the issue for me with
pull down menus not showing. It also fixed the issue with the help menu
showing some screen atifacts in the upper left corner of the screen as
was reported by the other user with the same issue.
Thanks for the help.

I can confirm this same issue. I have two machines running

the latest updates and XFCE4, and I am seeing the exact same
behavior. I
have noticed that Thunar on these machines doesn't exhibit the issue

just about everything else does. Makes x2go pretty much unusable.
Also
have the same issue when running openbox on the x2go server, so it
doesn't
appear to be related to the DE running on the server. Issue appears to
affect Mac x2goclients as well as linux.
It seems to have occured on one of the servers machines with the
issue after
a recent OS update where the following packages were upgraded (I have
downgraded libxrender, gtk2, gtk3, to the previous versions and the
problem
still exists, I am not sure what other packages could have this
effect) :
What version of nx-libs are you using? You could try to use a nightly
build of nx-libs (https://sunweavers.net/blog/node/20) and see if
that changes anything. However, there's no nightly for Arch Linux, so
you need to build it yourself.
Currently using 3.5.0.32-2 (archlinux package version). I will take a
look at upgrading this manually if all else fails.
Otherwise try to downgrade more packages and find the one that breaks
things.
I would start with these:
upgraded libxfixes (5.0.2-1 -> 5.0.3-1)
upgraded mesa (12.0.2-1 -> 13.0.0-1)
upgraded mesa-libgl (12.0.2-1 -> 13.0.0-1)
upgraded pango (1.40.2-1 -> 1.40.3-1)
upgraded libxtst (1.2.2-1 -> 1.2.3-1)
upgraded gsettings-desktop-schemas (3.21.4-1 -> 3.22.0+1+g6f52ab5-1)
upgraded gnome-themes-standard (3.20.2-1 -> 3.22.2-1)
upgraded libxv (1.0.10-1 -> 1.0.11-1)
upgraded libxrandr (1.5.0-1 -> 1.5.1-1)
upgraded gtk2 (2.24.30+95+g876b5f7-1 -> 2.24.31-1)
upgraded gtk3 (3.20.9-1 -> 3.22.2+4+gc54f348-1)
upgraded xfconf (4.12.0-4 -> 4.12.1-1)
upgraded xfce4-panel (4.12.0-2 -> 4.12.1-1)
upgraded xfce4-settings (4.12.0-5 -> 4.12.1-1)
installed vte3 (0.46.0+5+g398a3f8-1)
upgraded xfce4-terminal (0.6.3-3 -> 0.8.1-1)
upgraded xfdesktop (4.12.3-2 -> 4.12.3-3)
I will start downgrading these suggestions to see if I can localize
which one seems to cause the issue. I have already downgraded several
of them.
upgraded wayland (1.11.0-1 -> 1.12.0-1)
You are not using wayland, are you?
No, I am not using Wayland, however the arch packages for gtk3 and
mesa pull in wayland as a dependency.
Lately whenever I launch GTK+ applications over x2go, the
pull-down menus are usually not displayed properly or at all.
For example, if I launch the Xfce Terminal, I see the usual "File",
"Edit", "View", "Terminal", "Tabs", and "Help" labels in the pull-down
menu bar. If I click on these, they become underlined as though they
are active, but the corresponding pull-down menu doesn't (usually)
appear. Instead, a single pixel in the upper left corner of my desktop
turns white. The only exception is when I click on "Help" -- the first
time I do this, I do get a pull-down menu, but it's attached to the
upper left corner of my desktop, not to the "Help" label in the
Terminal
window. The menu is very small, though, and I need to scroll through it
to see all the entries. The second or subquent times I try to view the
"Help" menu, I just get a single pixel.
This sounds like a window manager problem.
Similar behaviour is observed in most other GTK+2 and GTK+3
applications, such as the GNOME Terminal and the GNOME Character Map.
The problem is reproducible when launhcing LibreOffice with
SAL_USE_VCLPLUGIN=gtk2 or SAL_USE_VCLPLUGIN=gtk3, but not with
SAL_USE_VCLPLUGIN=kde4 or SAL_USE_VCLPLUGIN=gen. Some (but not all) of
the applications output error messages like this to the console when I
try to activate a pull-down menu:
(gucharmap:26208): Gtk-CRITICAL **:
gtk_widget_get_preferred_height_for_width: assertion 'width >= 0'
failed
(gucharmap:26208): Gtk-CRITICAL **:

(gucharmap:26208): Gtk-WARNING **: Negative content width -7

extents 4x4) while allocating gadget (node arrow, owner GtkMenu)
Googling for these messages leads to bugs regarding xwayland and HiDPI
monitors, which does not fit in here (e.g.:
https://bugs.documentfoundation.org/show_bug.cgi?id=99508), but they
sugges using
SAL_USE_VCLPLUGIN=gtk
Does that help?
Anyone know what the cause might be and how I can work around it? I'm
running x2goserver-4.0.1.19 on an openSUSE Tumbleweed server and
x2goclient-4.0.5.0 on an openSUSE 13.2 client. The client desktop
environment is KDE 5.
Have you checked if it works at all without x2go?
Uli
At this time, I can confirm everything works properly on a local X
console - this problem only occurs when using X2go to access the
servers in question.
