Tried and reported on English UserGuide. Just reran again. Same difference.
Funny enough, the German UserGuide under /de/ compiles and displays…

Try again with English version.
After multiple reboots, still broken as reported.

Yes. But unproven for this case. UserGuide.pdf is broken for a long time
now on PDFkit based viewers.
UserGuide includes countless inludes/images. As for example PNG, and
PDF, and minipages…
In case of PNG they are probably just not optimised.
With PDFs they look like too big *and* trigger the problem?

double digit percentage savings on average.

Not overall, as those e.g. dictionaries take up a big chunk.
But I do not have a solution for making *them* smaller.
What I do see is that image files *can* be made smaller *easily*.
With pngout, advpng, optipng, trimage, imgopt, svgclean,…
Regardless whether they trigger the reported bug, that should be done
once, before shipping, saving thousands upon thousands of installed
bytes on user's machines.
