In GTK+ all widget layout & drawing is done in idle handlers within the
GTK+ event loop. So you need to make sure you return control to the
event
loop fairly often, and that you don't consume all the CPU time in other
higher-priority handlers like timeouts.

I don't think Glade would cause this problem, as it only uses fairly
simple
code to create the widgets.
