--- Comment #2 from V Stuart Foote <[email protected]> ---
Reproduced with default image handling. However this is not a bug.

Each image inserted to LibreOffice canvas gets its own handling. Key is to use
the image's context menu "Compression..." dialog to set handling for each when
default scaling is too course. The PNG image with the 26 May event is being
down sampled in resolution too far so appears smeared--you can adjust that but
the exported PDF will grow.

And, when exporting to PDF you can set the 'Lossless compression' as well as
the export 'Change image resolution to' DPI. But that can "smear" the images.

Also, should use the PDFIMPORT_RESOLUTION_DPI environment variable set higher
(default is 96 dpi) to control the bitmap resolution of any imported *OR*
exported PDF graphic used within the LO modules. 

Some mix of those controls should resolve with those steps and result in the
source PNG and JPEG image graphics at some higher resolution as set in the
"Compress..." dialog, as well as any pdfium "inserted" PDF at full resolution.

I was able to get the resulting PDF to closely match the combined size of the
two inserted images so at ~18.2MB. Too high a resampling DPI and the resulting
PDF export grows too large to process.

Please retest.
