Well, if you think that 18 seconds to scroll a page is normal, you could
have closed this earlier without making me flashing bios and installing
software. I'm sure there's something wrong in this terrible scrolling
lag, not expected even on a cellphone nowadays...

Title:
  Scrolling takes 5 seconds holding down arrow key at 100% zoom

Status in libreoffice package in Ubuntu:
  Won't Fix

Bug description:
  At 100% zoom, I count about 5 seconds to scroll from first to second
  page by holding the arrow-down key. CPU is not occupied by any other
  program.

  At 180% zoom, I count about 18 seconds to scroll from first to second
  page by holding the arrow-down key.

  At 180% zoom, a two-pages text-only document takes less than 2 seconds
  to scroll from first to second page by holding the arrow-down key.

  It becomes faster (not much) when the same image covers a smaller
  area.

  From settings, I've tried to maximize the graphics memory, and to
  enable/disable hardware acceleration and antialiasing, but it doesn't
  help.

  The problem persists in LibreOffice 4.3.5-rc2 from ubuntu PPA.
