[FirefoxNightly] pdf fonts misrendered when using Nightly on flatpak

[marcosps]

Mentioning a bug from mozilla/pdf.js#10352

Is there any test to make both "normal" Firefox from Firefox from inside Flatpak? Should it have differences?

[marcosps]

This is still present in today's update of Nightly in flatpak.

I cannot reproduce it on my setup (Fedora). Please double check that you're using gnome platform from the flathub and not from gnome:
flatpak info org.gnome.Platform
look for Origin: flathub. There's been some issues with fonts and older gnome platform.

If that's okay or won't fix the problem, run package as:

flatpak run --command=sh org.mozilla.FirefoxNightly
FC_DEBUG=20 firefox -no-remote > fc_output

Attach fc_output to the report or try to lookup the replacement font for the serif as it seems the be the font family in the document.

You can also run fc-match serif for getting the used font as metioned in issue #111.

Here is the output of fc-match serif:
DejaVuSerif.ttf: "DejaVu Serif" "Book"

Nightly is using gnome.Platform 3.26, which seems to be not updated since last November:

@xhorak Can provide you more info, or is this is enough to check what's the problem ?

[marcosps]

@xhorak Can I provide any other info to help you guys in solving this issue?

[thebitstick]

Same issue on Nightly.
Runtime/SDK should NOT be 3.26.
Needs to be set to 3.32..

[marcosps]

Same issue even after the recent update of Nightly: 68.0a1 (2019-04-16) (64-bit)

[marcosps]

@xhorak is it possible to change the SDK version as @thebitstick suggested?

[marcosps]

Now this issue happens even on the stable FF on Flatpak: 114.0.1 (64-bit)

on evince it works great:
