I have seen the same behavior.  I want to create some images for posters
in my lab, but the time has gone up roughly 7 to 10 fold for images at
the same settings as before.

An additional problem is that 2D label letters are not properly
rendered, with the result looking like the letters have lost their tops,
being sliced off at a slanting angle.  There is scattered "debris" as
well in the images.

In a completely rational society, the best of us would aspire to be 
_teachers_ and the rest of us would have to settle for something less, 
because passing civilization along from one generation to the next 
ought to be the highest honor and the highest responsibility anyone 
could have.     - Lee Iacocca
