the file
Product: LibreOffice
Version: 5.4.0.3 release
Hardware: All

Status: UNCONFIRMED
Keywords: bibisectRequest, regression
Severity: normal

Simple example file from the Candy template
If the attached file, made from the Candy template, is minimized, then the file
size is not reduced much.
This happens because of the 4 large PNG inside, only one gets converted to jpg
and reduced in size.
1. Open attached file in Impress
2. Tools - Presentation Minimizer
3. Press Finish without changing any setting
-> the file size is changed from 1.6 Mb to 1.2, which is not a lot
Version: 26.2.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: c7b3ea692f293346fbbdf2a391d9d971c34fa1f2
CPU threads: 8; OS: Linux 6.8; UI render: default; VCL: gtk3
Locale: hu-HU (hu_HU.UTF-8); UI: en-US
Calc: threaded
Works like this since this range in 6.0:

but, nothing is suspicious about these cleanup commits.
Anyways, just before this commit it was not good either: nothing was
compressed, which is another regression compared to 5.3, where all images were
properly compressed.
Unfortunately, under linux bibisect repos the oldest of 5.4 is already bad, the
latest of 5.3 is still good -> bibisectrequest.
