<pre>I tried on libreoffice-6.2.8.2 (last version available on i386).
I did not find how to install debug symbols, if needed.
I ran with "perf" for 10 seconds, with LibreOffice idle for 1 hour with no
document open, the resulting perf.data is 3.9 MB, do you need it?
Using "perf report", the first lines are:
