Steps to reproduce:

1. It is necessary to update to Nightly build on November 6 or later.
2. "Enable multi-process Nightly" option must be enabled.

It looks fine for me with the 64b version on Win 7. Maybe it's specific to Win 10.

Could you install the tool mozregression to narrow down a regression range.
See http://mozilla.github.io/mozregression/ for details.

Run the command "mozregresion --good=2016-11-05" then copy here the final pushlog from the repository mozilla-inbound.

You can swap the pref layers.gpu-process.dev.enabled to false in about:config, font rendering should be like previously (restart Nightly to apply).

Could you copy here the "graphics" section of the page about:support, please.

Anyway I think your issue is already reported in bug 1315568.

Yes, you are right.
