That commit simply made Cairo being available by default, if found on
the system. It didn't change any code. Are you saying that non-Cairo
build shows this problem as well, after that commit? Or is the
problem limited to Cairo builds on your system?

In general, display features that need GUI framework should be turned
on from after-make-frame-functions or server-after-make-frame-hook to
work reliably in daemon-based sessions. However, if this used to
work, it would be good to understand which change broke it. But I
doubt that the commit you identified is the culprit: I see the same
behavior on MS-Windows, where Cairo and the commit you pointed to have
no effect whatsoever.
