@Telesto : for some reason, I can't even get your test file to load in my current master build when running an allocation trace.

In fact, I can't get it to load at all, LO just hangs, requiring force kill.

It won't load in

either.

I tried testing this with a brand new 2 slide ODP file.

1) I inserted two graphics from the gallery into slide 2

2) Then Cmd-A in Slide 2 to select all objects, and Cmd-X to cut those objects

3) Switch to Slide 1 and Cmd-V.

4) Repeat in reverse order to cut and paste from Slide 1 to Slide 2.

5) Repeat the whole cycle several times.



Persistent memory usage seems to hover around 91.5Mb with

Version: 6.2.0.0.alpha0+

Locale: fr-FR (fr_FR.UTF-8); Calc: threaded

No repro really for me, as memory usage seems to remain pretty static.


@Telesto : Does it depend on the number / type of objects being cut/paste ?

Probably, the presentation in question has quite a lot of images. Little more than 1000 on the sheet in question.

File is opening fine for me, takes a while though.

Seems like bug 121778

Dear Telesto,

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 https://www.libreoffice.org/download/

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 https://downloadarchive.documentfoundation.org/libreoffice/old/

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: https://web.libera.chat/?settings=#libreoffice-qa
