Details:

Run this


clear all
fn="test.png";
delete(fn);
plot(1); 
print(fn);
exist(fn)


You will see a fltk window with title "Figure 1" and test.png is created. Then
minimize the window and run again. This time test.png isn't created. If you
now restore or maximize the figure window you might notice a slight delay and
test.png gets created.

I've tested this in debian wheezy, xfce 4.8.0.3, Octave 3.8.1 and a current
dev build (79f69742971a). A friend was also able to reproduce this with LXDE
but not with gnome.

I think this could also be related to bug http://savannah.gnu.org/bugs/?40215

Any ideas what I could test further to track down this?

libgl2ps0 is 1.3.6-1
