You have been subscribed to a public bug: When creating a GtkWindow with set_decorated(False) the window apparently still adds title bar and frame extents to its size. See attached python script. I expect it to open a square window of size 100,100, but what I get is a rectangular window of size 102, 129.
$ python3 undecoratated.py configure-event w=100 h=100 origin=(1, 51, 78) configure-event w=100 h=100 origin=(1, 51, 78) configure-event w=100 h=100 origin=(1, 51, 78) configure-event w=100 h=100 origin=(1, 51, 78) configure-event w=100 h=100 origin=(1, 50, 50) configure-event w=102 h=129 origin=(1, 50, 50) configure-event w=102 h=129 origin=(1, 50, 50) This affects Onboard, but not in Saucy's default configuration where override redirect mode is enabled. With OR disabled, the (undecoratated) keyboard window and floating icon change size every time they are shown.
