I can verify that the default behavior is to redraw pages on scroll, but not 
some of the other details for R14.0 on Wheezy.  Changing to "Aggressive" 
memory usage speeds up page display and thumbnails are remembered.  It's 
still possible to see a X page flash if you scroll very quickly but the 
overall speed in the default and aggressive setting is good.  It's about as 
fast or faster than Okular.  This is with a 2008 Thinkpad x61s.  

For fun, I fired up an Etch VM.  A small pdf rendered instantly, but a larger 
one had the Xs, but was still speedy.  That's basically what I remembered.
