You could take a performance profile of the slow down.

Install debug packages for LibreOffice:
https://wiki.ubuntu.com/Debug%20Symbol%20Packages

Install perf and FlameGraph and do the trace:
https://wiki.documentfoundation.org/Development/How_to_debug#Performance_debugging_.28perf.29

So you run LibreOffice, then in a terminal you say

perf record -F 200 --call-graph dwarf,62000 --pid=`pidof soffice.bin`

Then you open the slow file.

You exit perf by Ctrl-C in the terminal.

Then you can create the SVG flamegraph.
