When a widget (including your window) is resized, the widget generates
an event to be redrawn, so the call to 'queue_redraw()' to force the
redraw of the window is not needed.
The problem is in your code: In a simple loop you are performing many
resize operations. Gtk and GTKmm is working based on events, so every
time you call to resize, an event is generated and queued, and all
generated events are processed once the loop is finished (the control
returns to main loop and new events are processed).
You should change the implementation of your function and use a timer,
in which at every timer callback an update should be done. For more
