I have LibreOffice version 5.2 (see below for exact system specs) on a Macbook laptop. Generally I am happy with this software, but from time to time it would lock up, busy, unresponsive for a reason I don't understand. I also couldn't pinpoint certain action that triggers this behavior. I mainly refer to Writer, but it might also happen with other LibreOffice applications. The "top" command shows nearly 100% CPU utilization when this happens. Usually it will resolve, but it can take many seconds before it quits the unresponsive phase. Has anyone experienced this with the MacOS X version described below? The hardware has 8GB RAM and 5th generation (Broadwell) Intel i5 CPU, so it should be adequate for this job, even with web browser and a few other applications open.

My typical usage pattern is: I open 5-10 documents at the same time, mostly writer docs saved in ODT format. These are smallish documents (<100 kB each).

Info from "about LibreOffice" box:

Version: Build ID: d54a8868f08a7b39642414cf2c8ef2f228f780cf CPU Threads: 4; OS Version: Mac OS X 10.11.6; UI Render: default; Locale: en-US (en.UTF-8); Calc: group

Thanks, Wirawan

Please try resetting the user profile, sometimes solves strange issues. Usually it's enough renaming/deleting the file "user/registrymodifications.xcu", it affects all the options in Menu/Tools/Options, and the files "user/basic/dialog.xlc" and "scrip.xlc" are overwritten, additionally custom colors in "user/config/standard.soc" are lost.

UPDATE: I found the action that almost always causes the busy CPU syndrome. One obvious action is resizing a window, or moving a window. Then the CPU usage of soffice becomes 100% for about 1 minute.

Have you tested with Menu/Tools/Options/LibreOffice/View - OpenGL, enable?
