--- Comment #49 from Alexander Larsson <alexl at redhat.com> ---
I tried the latest version, and it seems better but it still has the issue
behdad disliked. I.e. In my case I have on the outside (minimal example):

/usr/share/fonts/dejavu/DejaVuLGCSerifCondensed.ttf
/usr/share/fonts/dejavu/DejaVuSans-Bold.ttf

And, in the sandbox I have:

/usr/share/fonts/dejavu/DejaVuLGCSerifCondensed.ttf
/run/host/fonts/dejavu/DejaVuLGCSerifCondensed.ttf
/run/host/fonts/dejavu/DejaVuSans-Bold.ttf

I.e. one of the sandbox-only files covers one from the host, but not all,
and both host files are visible in the sandbox at a different location.

If i run fc-list in the inside it will show:
/usr/share/fonts/dejavu/DejaVuSans-Bold.ttf: DejaVu Sans:style=Bold
/run/host/fonts/dejavu/DejaVuLGCSerifCondensed.ttf: DejaVu LGC Serif,DejaVu LGC
Serif Condensed:style=Condensed,Book

I.e. the "shadowed" host font is not visible in the cache. This is not really s
showstopper for me, but I can see why behdad dislikes it.

Anyway, I would *love* to get some review on this so we can get a release with
it (so i can put it in the flatpak runtimes). The current behaviour is causing
really slow first-time startups of flatpak:ed apps.
