Screenshots during and after problem, confirms previous comment
I wasn't sure if it was relevant when I started making this comment, but I just
now approved some updates, with LO open, and weird things are happening now. I
managed to add one sentence to my long document, and then the LO window was
greyed out (indication by Metacity desktop that the process is CPU bound). I
noticed that the Adobe Flash update included a mention of an update to the
noto-sans (IIRC) font. I also saw from ps that "unity-settings" and "fc-cache"
were about 95% busy.
$ ps ax | egrep -i "(unity-sett|fc-cache)"

soffice got the bulk of the rest of the CPU time. When those two processes
finished running (after several minutes), soffice went to 100% CPU. As it's
currently stopped me from working, I thought I may as well take the time to
report it, as it may be related.
Ah ha! Yes, I just noticed that the page header text on display has changed
(wrong character style within my name). It's also now locked up completely -
I'm going to have to kill it. The window got obscured while I was making this
report, and when I just brought it back to the foreground, it displays with the
overlapping contents of the windows in front of it: it can't even refresh
properly. (So: locked up for about 15 mins.)
I did manage to grab a stack backtrace; it's below. Oh, and how fortunate that
I took the time needed to do this, live: LO has *just now* returned to normal
(apparently) without me needing to kill it. And without me doing anything, the
title is now drawing correctly. By great good luck, I got screenshots of LO's
window, both messed-up and recovered-by-itself, which I have attached.

At the very least, LO interacts very badly with the font cache during updates,
with no hint to the user about what's happening.
