Some of the clipart I am using in an Impress presentation disappears and/or is wildly enlarged if saved as PPT or PPTX format. The size of the graphics is not changed, its contents is wildly enlarged and thus cropped.
(Test file is in a comment below, as I cannot find an option to include it in the original bug report.)
Steps to Reproduce:
1. Open test file from the following comment: "Clipart of microscope.odp"
2. The file should show a clipart of a microscope and another of a schematic DNA string and a microscope.
3. Save as PPT or as PPTX
4. Open saved file (either in Impress or in PowerPoint)
For the microscope, only the outline around the position is seen. Of the DNA string, a small and wildly enlarged bit is seen.
The PPT and PPTX files should contain similar graphics as the original ODP file.
User Profile Reset: No
The result is similar whether tested as roundtrip in Impress, or opened by MS PowerPoint. This has been tested in the newest fresh LO version, but the problem has been present also in earlier (6.x) versions.

Dear Lars Jødal,
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
Thank you for helping us make LibreOffice even better for everyone!

Given that the PPTX file opens similarly in LO and in MS PowerPoint, the problem seems to be in the PPTX and PPT export filters.
Comment 3 indicates that the graphics format is changed by the filter. As I understand it, the SVM graphics format is native to OO/LO, for which reason a conversion is probably necessary for the export. The problem then appears to be the scaling in the conversion.
A similar problem then seems to be described in bug 94363.
