I am using glade-3.20 on Ubuntu-16.10 with gtk-3.20.
Notably, this file opens but does not display its contents correctly
when I try to open it with glade-3.19 on Ubuntu-16.04 with gtk-3.18

In Gtkmm (C++) you can overload the on_draw() function with your own.
This might give you a foothold in the on_draw() routine that is called
after a redraw event occurs. I guess in GTK you would have to connect a
callback function to the "draw" signal. Might help.??
