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.

Code
cut_-_memory_use.scad
http://forum.openscad.org/file/n10510/cut_-_memory_use.scad
Video (boring - sorry for all the waiting, but the flashing takes time and
is inconsistent)
v4_resampled_2.mp4 (8MB, 7m37s)
http://forum.openscad.org/file/n10510/v4_resampled_2.mp4

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.
