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'm pretty sure this is more fallout from the change mentioned in the 
upstream bug [1] linked there, but why it only manifests under the 
cygwin X server, I don't know.

I would suggest perhaps raising a bug against gtk+, although idk how 
much attention that will get.
