I'm not sure if this is a cygwin problem, a gtk problem or something

Thanks for reporting this issue.
I have 3 remote machines, one running servers, one running Ubuntu 16.04
and the other 2 Debian stretch.
Remote applications on the Debian machines from a Cygwin xterm (or
putty) don't work correctly. An application (gnome-terminal and nemiver
being the two mostly use) will open correctly and keyboard is (mostly)
OK but mouse input doesn't work.
For example clicking a menu heading will place a line under the heading
in the GUI but the menu doesn't open. Note that I get the same failure
when using the keyboard shortcut keys (e.g ALT-F <> File). Sometimes a
part of the menu (maybe one or 2 lines) will appear in the top left of
the Desktop and can be scrolled through and selected using the keyboard.
The window controls (minimise, maximise, exit) work correctly.
I can reproduce this using a debian stretch VM.
It occurs with the cygwin X server in both windowed and multiwindow
mode, so that would seem to exonerate the cygwin multiwindow mode WM.
The menus work correctly using the debian X server with no WM, though.
I get (lots of ) GTK error messages in terminal like this as I try to
use the GUI:
I've come across this bug filed against gtk in Debian which seems
I'm unclear then whether this is a Debian/gtk issue or a Cywin/X issue
(given that Ubuntu->Debian is OK).
I'm pretty sure this is more fallout from the change mentioned in the
upstream bug  linked there, but why it only manifests under the
cygwin X server, I don't know.
Can anyone advise where I go from here?
I would suggest perhaps raising a bug against gtk+, although idk how
much attention that will get.
