Looks like the decisive blow, indeed.  Admittedly, inhibiting double
buffering was a gross hack too.  But I doubt Jan had any alternative
solutions at hand when he coded that.

Do I understand correctly that the entire effect of setting double
buffering off is encapsuled in the case where a GDK_EXPOSE event is
handled?
