Bug ID: 120727
Summary: Excessive CPU usage under normal use (typing)
Product: LibreOffice
Version: 6.1.2.1 release
Hardware: All
OS: Mac OS X (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: libreoffice-bugs@lists.freedesktop.org

Example of problem document
Unfortunately past few version of LO have been CPU hogs in normal usage
(typing), causing significant lag and detracting from the use experience (as if
typing via a remote desktop connection)
Have tried resetting the profile, no change.
I don't remember when this has changed - but it has been a issue for the past
few months (at least since 6.0 - I normally update regularly)
When I type in this document with a graphics object on the page,
the CPU usage is 50% on a 2.6GHz 8th Gen Core i7.
LO 6.1.2.1 on macOS 10.13.6
Open CL is not used. Auto spellcheck is off.
Expected behaviour:
CPU usage low (<10%)
"snappy" UX whilst typing
Actual behaviour:
CPU usage 50% of a 2.6GHz core
typing has (tens of ms?) lag
