We're seeing some problems with the rendering of single-page PDFs. We're aware of this problem. We're launching the new renderer any day now(tm), which will hopefully solve them.

Can you please clarify, what is the currently deployed renderer and what will the new one be? The current one on en.Wikipedia appears to be produced by Skia/PDF m58 and created by (presumably headless) Chromium. I have found a page on this MediaWiki for Proton, but it is not informative about rollout status. Also, what is Skia/PDF m58 and is it about to change?

Hi!

Skia is an open-source graphics library, it's been relevant for us for quite some time so it's not a new thing: https://en.wikipedia.org/wiki/Skia_Graphics_Engine

https://www.mediawiki.org/wiki/Proton is indeed the new renderer. It's been running in the background for testing for weeks, but we haven't actually made the switch yet. (Which I thought we would have. My apologies for saying "soon!" a bit too often. This thing that always seems to be two weeks away.)

OK, thanks. Further to that I have now found out that the current renderer is Electron, which also uses Chromium (though whether headless or not I don't know). It take it that it will remain unchanged until the relevant two weeks for Proton finally make their appearance.

Yes, sorry, should have clarified that as well.
