Bug ID: 120561
Summary: LibreOffice Writer drains battery by 100% cpu load
Product: LibreOffice
Version: 6.0.6.2 release
Hardware: All
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
Description:
Working on a document for a couple of weeks now, from some point on I realised
that writer kicks the cpu load to 100% right after opening the document and me
doing nothing at all (no typing, no re-arranging). There is a single extension
in use: Zotero LibreOffice Integration 5.0.14, but even if disabled, the cpu
load remains at 100% just after opening the document.
The document itself consists of 25 pages with four frames, each holding a
table, which I'd rate as nothing fancy nor complicated. Not even the 'track
changes' feature is activated. There are references to the tables.
The impact is a dramatically decreased battery life time of the system and
significant heat production.
After playing with the UserProfile Settings the problem seems to be triggered
by having Umlauts in the name field of the user data. If I drop the Umlauts,
close Writer and double click my document again, libreoffice writer starts up
and maintains a reasonable cpu load. If I reintroduce Umlauts into the name
field, exit libreoffice and open the document again, the 100% cpu load is back.
Steps to Reproduce:
See description. Not reproducible with an empty document.
Actual Results:
CPU load consumed by writer is constantly 100%.
Expected Results:
Reasonable cpu load.
Reproducible: Always
User Profile Reset: Yes
OpenGL enabled: Yes
