* on an iPhone 4 or equivalent high-DPI device: * Go to http://test.m.wikipedia.org/wiki/San_Francisco * open "Culture and contemporary life" section * scroll down a bit to the photo of SFMOMA High-DPI responsive images aren't being loaded in sections beyond the summary section. The SFMOMA photo in the San Francisco 'Culture' section should show a lot of detail on the diagonal lines on the central circular slanted roof, but shows blurry and pixelated instead. Probably needs an explicit call to $(...).hidpi() in the appropriate event handler after loading the sections. This is likely closely related to bug 41287.
The event 'mw-mf-section-rendered' is triggered after a section has rendered $( window ).on('mw-mf-section-rendered', function( ev, container) { $( container ).find( ... ).hidpi(); } ); should fix this? Not sure how to use hidpi though - can you point me at the code or look into this yourself?
The hidpi code is in core: https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/core.git;a=blob;f=resources/jquery/jquery.hidpi.js;h=70bfc4ea3c664570102bd697140912fedfd98373;hb=HEAD $(foo).hidpi applies the 'srcset' stuff to any <img> elements found within the given selection, so assuming container is the container for the newly shown section this should work: $( window ).on('mw-mf-section-rendered', function( ev, container) { $( container ).hidpi(); } ); It should be idempotent if run over the same DOM subtree twice, so it should be safe to run it multiple times if need be.
