@Jdlrobson - pulling this back into the backlog as we've had a number of bug reports on this. Do we know why it was originally moved to tracking?

We're actively working on Chromium PDF as we want to abandon the ElectronPDF extension. IMHO, first, we need a spike to find a way to reproduce those issues.

I don't think it might be article-dependent – probably just a server timeout(?) or something if there are lots of different images and maybe if someone's connection is slow (though it should be rendered server-side). I haven't done any further testing, though.

@ovasileva I have been unable to reproduce this one. I tried on a bunch of browsers including firefox and chromium. I tried the example article and bunch of other articles with lots of images (ex. Barrack Obama). I also played with some slow connection, but so far I am still unable to reproduce.

@ABorbaWMF Maybe try testing using a VPN (e.g. to somewhere in East or Southeast Asia), or testing when there's a higher load on the WMF servers?

Testing using the PDF renderer.

So far I have not reproduced this using the PDF renderer. I also tried a host of articles while working on T195991. Marking this resolved for now. We will retest it once the final version is live on production.
