Something else that I just noticed;

I had two documents open over the past night, I created both about the
same time around 11pm according to the file's modified timestamp. One
had about 3 pages of text, the other had three words.

Today at 1:22, the first and larger document exhibited the usual choppy
scrolling behavior and the other did not. I closed the first document
before I came across this observation.

I'll try to keep notes here on what I'm noticing, perhaps there will be
some nugget of useful information. This bug annoys me greatly...

Title:
  libreoffice slow on screen scroll and retries the scroll several times

Status in “libreoffice” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: libreoffice

  When I have word document opened in libreoffice for more than a day, after that time the scrolling of the scroll bar takes a minute to finish. Redrawing the screen seems to fail, in the sense that subsequent sentences are overlapping (showing only half of one of them)
  I cannot produce a screenshot, because the process consumes more than 50% cpu. To describe what happens, imagine a scroll of half a page or so: it start the scroll, hampers on redrawing the bottom lines (when scrolling down), then finishes after about 10 seconds with >50% cpu activity. When it reaches its 'destination', it restarts from the beginning (top) and show the same behaviour several times.

  I have this problem with a word .doc file and adding comments to text,
  but I do not know if this is related.

  I have switched off the 'java' option in the preferences (having read about that solving the problem somewhere), but that doesn't help.
   
  closing and reopening the document resolves the problem: fast response to scrolling the mouse.
