The most common cause is an invalidation in the expose routine which
basically creates a tight loop.

For something like a calendar widget, I would use Gtk.Style instead of
going directly to cairo, since then your widget is more likely to look
integrated for people using different themes.  If you are interested in
seeing how something like that can be done, there is a Calendar view in
my toy fitness log app.

There's a screenshot of it in action:
