incorrect rendering of output in firefox

[phi-gamma]

Reported by Luigi.

I’m testing with xpdf, mupdf and okular (poppler) which are all okay. Anyone know what ff uses for rendering?

pdf.js

[phi-gamma]

this is caused by the compatibility hacks for fontspec et al

@khaledhosny thanks! we should compile luatex and $EDITOR with emscripten to get a complete, browser based tex environment.

Something’s wrong with caching; happens with luatex-plain but not with context; http://www.ntg.nl/pipermail/ntg-context/2013/073157.html

[khaledhosny]

If anything is at error here, it is pdf.js not anyone else. No point for making workaround for it, those aren’t only the PDFs it renders badly.

This doesn’t appear to happen anymore with the latest code. @eroux can you test e.g. the luaotfload manual if it still results in garbage with firefox?

[eroux]

Manual with latest code is really garbage (maybe more than before) with Firefox 22... Sorry :)

Does it get better if you apply this patch to luaotfload-merged.lua:

diff --git a/luaotfload-merged.lua b/luaotfload-merged.lua
index 81e3fec..9d708bf 100644
--- a/luaotfload-merged.lua

?

[eroux]

Well, it's pretty much the same...

[phi-gamma]

Ah, sorry, forgot to mention that you need to delete the font cache.

[eroux]

Oh, sorry, it works even without your patch if I remove the cache.

[phi-gamma]

Great, closing this one.
