demo SVGZ


I have experienced sluggishness, freezing and crashes upon insertion of many compressed SVG (svgz) graphics.
Moreover, some are displayed improperly and black and white.
See the attached demo compressed SVGZ.
Compare how they look in Inkscape and how they look in LibreOffice.

Best wishes,

BTW, this is also true when working with not that many uncompressed SVG graphics.
Comment 2 Buovjaga 2016-09-21 19:11:52 UTC
I get the sluggishness even with a single inserted file (demo_01.svgz).
It is worse in 5.2 than in 5.3.

Callgrind output from master

This is taken from the action of just typing "f" to the Writer document after the SVGZ has been inserted.

Dear Daniel Grigoras,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)

If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword

Feel free to come ask questions or to say hello in our QA chat:

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
