Test doc that gives high CPU usage / typing lag

Version: 7.0.0.2
Build ID: c01aa64b6c3d89ebe5fe69c28c7adb24eb85249c
CPU threads: 12; OS: Mac OS X 10.15.6; UI render: default; VCL: osx
Locale: nb-NO (en_NO.UTF-8); UI: en-US
Calc: threaded


Basic typing in a table is laggy - using >60% of a CPU core Core i7 on a retina MBP 2018.

This is a problem because I use a laptop and this makes it warm and drains the battery with basic document editing, in addition to poor use experience.

Hello info@snowflake.as ,
I believe this issue might be fixed now after
https://git.libreoffice.org/core/commit/27a4aea50a9efa5c839b0ae2de1f9f14a7782f11.
Could you please try to reproduce it with a master build from
http://dev-builds.libreoffice.org/daily/master/ ?
You can install it alongside the standard version.
I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the master build
