--- Comment #23 from Adam Goode adam@spicenitz.org --- (In reply to Bojan Smojver from comment #22)
The patch, as was delivered in F25, changed the size of fonts significantly. Windows changed size a result and most fonts rendered too tall.
Too tall? Did you mean too short? If fonts are rendering taller now, then that is another problem that's not yet been investigated.
Either way, I will comment on the upstream bug and see if there is some autohinter tweak that could be made to keep this metric from changing.
