See my issues with designs with lots of elements.
The multiple repaint shows up here, sometimes it flashes white/showing/white
a number of times.
Resizing the window with constant repaints is hopelessly slow.
Changing the view is really slow, often causing 'Not Responding'
Changing it to larger=false (100x100) is just usable.
Removing difference or using Thrown together works normally.
This is not version dependent, same in 2014.03, later versions are
marginally better.

Video (boring - sorry for all the waiting, but the flashing takes time and
is inconsistent)

I'm happy to raise an issue of someone can supply words to describe that
behaviour more concisely.

Hi Michael, I can confirm the same bad performance here. Tried on both
2014-11-09 and 2014-12-04 versions on two Win64 machines.

Although it is a bit sluggish, I don't have any "real" problems here.
Upgrading to the integrated graphics in your i7 3xxx processor will
definetely solve this problem for you.
