Bug ID: 162644
Summary: 100% CPU usage and slow export to PDF when opening
document with Writer
Product: LibreOffice
Version: 24.2.5.2 release
Hardware: x86 (IA32)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
Description:
Hello,
When I open a specific file with LibreOffice Writer, the CPU usage of a thread
quickly jumps to 100% and stays there even if I'm not interacting with the
software.
Additionally, when trying to convert the document to a PDF using the CLI, the
process takes around 10 seconds on my machine, for what should be almost
instant.
The affected document is very simple, and somehow involves a shape in the
header, and you need multiple pages to reproduce it (If you delete all pages
but the first one, the usage goes back to normal levels)
Steps to Reproduce:
1. Open the affected document
2. Look at the CPU usage
-- OR --
1. Execute `libreoffice --convert-to pdf slow.odt` (It takes around 10 seconds
on my machine)
Actual Results:
The CPU usage is unusually high and the pdf transformation take a long time
Expected Results:
The CPU usage should be significantly lower and the pdf transformation should
take less than a second (Which happens if you remove the header)
Reproducible: Always
User Profile Reset: No
Additional Info:
The repro file can be downloaded from here (I don't know how to attach a file:
