Dunno why this is, but some emoji are showing up small? Possibly only in text-emphasis marks? I thought it used to be all emoji, but emoji in normal text look fine now? Confused.
Could you attach the testcase used to create your screenshot, please?
test-case: <body style="max-width: 40em; font-family: sans-serif"> <p> TIRED:

Oops, here's the test-case properly
Also just to be clear, this is a webrendest layers-free bug. My only theory right now is that webrender should be doing some kind of special "emoji text snapping"?

FWIW, the rendering I see in Nightly (with webrender disabled, according to about:config settings) matches the right-hand version in your screenshot (i.e. with the smaller version of the text-emphasis glyphs). How does the sizing compare to regular ASCII letters used in text-emphasis? In my testing, I think the emoji sizing in text-emphasis matches the sizing of other text (i.e. both Latin letters and emoji glyphs match the smaller version of your screenshot.

I'm only seeing this on macos, so I think this might be another consequence of https://bugzilla.mozilla.org/show_bug.cgi?id=1397458

Here's a screen shot with capital T's next to it for comparison. (macos) Left: vanilla nightly gecko Right: webrendest + layers-free
Curious... what I see (with vanilla Nightly, macOS) looks to me much more like the right-hand version in your screenshot.
Maybe there's a minimum font size configured in one of the Firefox profiles?
https://gankro.github.io/blah/webtests/text.html has this case at the top, for anyone who wants to test this out.

(In reply to Markus Stange [:mstange] from comment #9) > Maybe there's a minimum font size configured in one of the Firefox profiles? I don't believe text-decoration glyphs are constrained by the font.minimum-size.* prefs, as they are required to be smaller than the text to which they're applied.
I can also reproduce the sizing difference, on today's nightly, with default settings vs webrendest+layers-free on a HiDPI Mac.

This seems to have resolved itself. I expect because we're using CoreText a lot more now.
