Is this a build with or without Cairo? (you snipped the part of the
bug report that would have told us)
Sebastian> In
Sebastian> FC_DEBUG=1 emacs -Q --font=:family=Hack:size=11
Sebastian> the 'size=11' is interpreted as 'pixelsize=11'.
Sebastian> fc-match :family=Hack:size=11 size pixelsize
Sebastian> does interpret it as point size.
Sebastian> Apart from that both
Sebastian> emacs -Q --font=:family=Hack:size=11.1
Sebastian> and
Sebastian> emacs -Q --font=:family=Hack:pixelsize=11.1
Sebastian> both yield the same error: "invalid font property: (:size . 11\.1)",
Sebastian> although according to fontconfig the pixel size is a double, too.
Sebastian> However, fractional pixel sizes may not make sense for Emacs at all. I

Sebastian> The following does work as expected:
Sebastian> emacs -Q --font=Hack-11.1
