¡Hola!

The only devtools patch I see on https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=a3f280b6f8d5&tochange=2694ff2ace6a is https://bugzilla.mozilla.org/show_bug.cgi?id=1174407

Michael could you please take a look while Patrick is in PTO?

¡Gracias!

The devtools changes in the changelist shouldn't trigger font-rendering issues... this really is an issue for the graphics guys.

If this is still happening, it's likely a dupe of bug 1220371.

This is likely fixed now. WebRender has different and more stable heuristics for when to apply subpixel AA.
