I can't reproduce this. But I have similar problems with other apps in
Gnome 3 and Xfce when I use the in-window menu. See attached image (I
don't have this problem in IceWM). Currently there are some bugs related
with this problem at bugtracker. If the window is resizable, I use this
hack at -applicationDidFinishLaunching:

  NSUserDefaults *defaults = [NSUserDefaults sharedUserDefaults];
  
  if ([defaults integerForKey: @"Resize"] == 0)
    {
      //Code to increase the width by 1 pixel.
      [defaults setInteger: 1 forKey: @"Resize"];
    }
  else
    {
      //Code to decrease the width by 1 pixel.
      [defaults setInteger: 0 forKey: @"Resize"];
    }


This works for me.

I think the problem is at gnustep-back, in the way how gnustep interact
with each window managers. But since I don't understand how it works, I
can't do anything in this way.
