>             Project: FOP
>          Issue Type: Bug
>         Environment: Windows 10.0.19045 Build 19045
> Java 17
> FOP 2.8
> PDF Images 2.8

> When including the PDFs of one of our customers, the layout gets messed up, turning this: 
> !image-2023-07-13-16-47-09-093.png|width=349,height=265!
> into this:
> !image-2023-07-13-16-46-26-626.png|width=350,height=284!
>  
> The customer recently switched to PDF 1.7, all of their PDFs get messed up ever since. 
> There are no FOP events in the log, checking the resulting PDF with _pdfcpu_ validates perfectly, even with strict mode on. 
> Setting strict-validation in the renderer also doesn't produce any errors. 
> The problem happens regardless of the version of FOP and fop-pdf-images used. The FO input for reproduction can be reduced to 
> {{<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format"}}
> {{xmlns:fox="http://xmlgraphics.apache.org/fop/extensions">}}
> {{  <fo:layout-master-set>}}
> {{    <fo:simple-page-master master-name="simple">}}
> {{      <fo:region-body/>}}
> {{    </fo:simple-page-master>}}
> {{  </fo:layout-master-set>}}
> {{  <fox:external-document src="PDF/input.pdf" />}}
> {{{}</fo:root>{}}}{{{}{}}}
>  
> Various problems regarding layouts are mentioned in the "Known Issues". 
> There is also the general statement _"Apache FOP currently generates PDF 1.4. If you include a PDF with a higher PDF version, the results may be unpredictable."_ to be found (That said, setting different versions in the renderer did not solve the problem).
> Please let me know, if this is out of scope for the project - and if it is, please provide me with any workarounds you might know of!
>  
> (Included are one of the originals together with its output, as well as an older PDF of the same customer which works as expected. )
