I can't say for certain, but I believe that your problem is probably
that you're scaling the surface to a 'unit square' (e.g. the X and the
Y axes go from 0.0 to 1.0) and then you are setting your text size to
30. This means that your text will be 30 times larger than your window
size. I doubt that is what you intended, and I think it probably is
hitting some maximum X server coordinate value and causing the
application to crash. Hope that helps
