Bug ID: 2045012
Summary: Split the Cantarell fonts into 2 for VF and
non-variable fonts
Product: Fedora
Version: rawhide
Status: NEW
Component: abattis-cantarell-fonts

Target Milestone: ---
Classification: Fedora
Description of problem:
Matthias Clasen pointed out that abattis-cantarell-fonts currently
includes both variable and non-variable fonts.
This duplication makes it harder for pango to choose the right font for
example.
We should split the binary package into two and only install the VF one by
default.
Version-Release number of selected component (if applicable):
abattis-cantarell-fonts-0.301-6
Steps to Reproduce:
1. rpm -ql abattis-cantarell-fonts
Actual results:
Contains both fixed and variable fonts
Expected results:
Probably Cantarell-VF.otf should be moved to abattis-cantarell-vf-fonts
subpackage
and made the default.

[Bug 1809989] New: By default install Noto fonts for Unicode scripts

There is currently movement towards protecting browser users from font
fingerprinting. This means refusing, by default, to load user-installed fonts,
which makes the set of fonts that each OS installs by default even more
important than before.
Firefox bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=1582687
W3C CSS WG issue:
https://github.com/w3c/csswg-drafts/issues/4497
Currently, Windows 10, macOS, Android, and Chrome OS provide broader
installed-by-default Unicode coverage than Fedora.
Examples of living scripts that have enough active users to make it to the list
at
https://en.wikipedia.org/wiki/List_of_writing_systems#List_of_writing_scr...
but are not supported by default in Fedora 31 include Javanese, Sundanese,
Batak, Balinese, Mongolian, and New Tai Lue.
Egyptian hieroglyphs is an example of a dead script the Fedora 31 doesn't
support out of the box but Windows 10, macOS, Chrome OS, and Android do.
To remedy this with minimal disk space impact, I suggest the same approach that
Apple took. Apple bundles with macOS those Noto fonts that cover scripts that
were not already covered by the previous installed-by-default set of fonts on
macOS. In the macOS case, the on-disk footprint of the Noto fonts that were
required to take macOS to Android/Chrome OS-competitive Unicode coverage was
only a couple of megabytes. (The fonts are hidden in /Library/Application
Support/Apple/Fonts/Language Support/.) In the case of Fedora, the set of Noto
fonts required to reach the Chrome OS / Android level of script coverage is a
bit larger than in the macOS case but should still be manageable.
Please install, by default, those Noto fonts that provide support for scripts
that are not properly supported by the fonts that Fedora already installs by
default.

[Bug 1784650] New: Fontconfig is slow, causing stuttering and
freezing
by bugzilla＠redhat.com
https://bugzilla.redhat.com/show_bug.cgi?id=1784650
Bug ID: 1784650
Summary: Fontconfig is slow, causing stuttering and freezing

Target Milestone: ---
Classification: Fedora
Description of problem:
Fontconfig is much much slower than on other distros, and it stutters or
freezes applications that use it.
Version-Release number of selected component (if applicable):
Name : fontconfig
Version : 2.13.92
Release : 3.fc31
Architecture: x86_64
How reproducible:
I can reproduce this bug on a fresh Fedora 31 vm with the Xfce desktop and
google-noto-sans-* fonts installed.
Steps to Reproduce:
1. dnf install google-noto-sans-*
2. run gedit on the attached example file
alternatively
1. dnf install google-noto-sans-*
2. open firefox and browse to https://www.wikidata.org/wiki/Q52 (page with lots
of languages)
Actual results:
It takes around 60 seconds for gedit to become responsive to scrolling and
input. Mousepad is faster but still slow.
It takes firefox upwards of 5 minutes to get to first paint on a page with many
fonts or languages, compared to a simpler page.
Expected results:
Gedit should load files with many fonts at a similar speed as other distros.
The page should load quickly, like on Debian and others.
Additional info:
I have tried to diagnose the source of this issue in many ways.
Running `perf trace` on what sysprof indicated was the most busy function
(FcStrCmpIgnoreCaseAndDelims), shows that every name of every font family is
being compared to every other name of every other font family. I do not know if
this is a normal behaviour of fontconfig.
I have noticed the amount of calls to "FcStrCmpIgnoreCaseAndDelims" and program
startup time both drop to a similar amount as Debian's when all of the
"google-noto" configuration files in /etc/fonts/conf.d/ are deleted (These
files are not present in Debian). However, this might not be the source of the
problem:
In the Debian vm, with a copy of my computer's /etc/fonts/, including the
google-noto files, (I took care to ensure that there would be no broken
symlinks) and /usr/share/fonts, fontconfig does not stall any programs. The
amount of calls to FcStrCmpIgnoreCaseAndDelims is also much lower as well.
This led me to believe that it was a difference caused by compiler flags but
this does not seem to be the case. I tried to replace the optflags in the
package, except for the rpmbuild required debug ones, and found no difference.
I also checked to ensure that it was not caused by GCC version differences.
Debian results for mousepad:
1,845,449 calls to FcStrCmpIgnoreCaseAndDelims
Time: 5 seconds
Fedora results for mousepad:
11,658,380 calls to FcStrCmpIgnoreCaseAndDelims
Time: 23 seconds
https://perfht.ml/2tleJxN
Here is a link to a Firefox profiler result of the wikidata page, where in the
flame graph you can see that Firefox is spending most of its time in
fontconfig. You can also see "FirstNonBlankPaint" is at 50 seconds in the
marker table.
TLDR: Fontconfig matching is slow with all google-noto fonts installed, unless
you remove the noto config files. Using the same exact font directory and
config directory (including the noto config files) on Debian does not cause the
same problem.

Classification: Fedora
With the transition to new forge-based fonts macros, the -common subpackage was
dropped, but some packages depend on that. They are now not installable on
fedora 32+ because that package is gone (only Obsoleted, not Provided).
This affects at least python3-weasyprint.
Additionally, the sdljava-demo package now has broken dependencies as well:
- /usr/share/fonts/dejavu/DejaVuSans-Bold.ttf
- /usr/share/fonts/dejavu/DejaVuSans-BoldOblique.ttf
- /usr/share/fonts/dejavu/DejaVuSans-Oblique.ttf
- /usr/share/fonts/dejavu/DejaVuSans.ttf
Probably those files were renamed with the forge macro transition.

A flaw was found in freetype in the way it processes PNG images embedded into
fonts. A crafted TTF file can lead to heap-based buffer overflow due to integer
truncation in Load_SBit_Png function.

There is a regression bug [1] that is affecting freetype 2.11.0-1 on Fedora 35.
This is blocking me from being able to provide the angband package [2] for this
version of Fedora.
From my perspective there are 2 ways to fix this:
A) Provide the 2.11.1-1 version that is already packaged for rawhide, this
brings other fixes besides the regression fix I need. I've been using this
version [3] on my F35 installation for the last 2 months and it seems to work
fine.
B) Apply the commit [4] that fixes this regression on 2.11.0-1, using this
patch [5], then generate a 2.11.0-2 version of freetype for Fedora 35.
I would appreciate if you help me fix this if it's not too much trouble.

Target Milestone: ---
Classification: Fedora
Description of problem:
I have this (per-user) fontconfig configuration to set my preferred sans-serif
font:
<alias>
<family>sans-serif</family>
<prefer>
<family>Noto Sans</family>
<family>Noto Sans CJK SC</family>
</prefer>
</alias>
It should fall back to "Noto Sans CJK SC" when displaying CJK characters. Since
F32 this isn't working anymore. CJK characters are rendered in a different
font, which I cannot recognize.
Digging through fc_debug logs, "Droid Sans" is appended right after "Noto
Sans", before "Noto Sans CJK SC" in the font matching list. Debug messages
confirm it's indeed Droid Sans getting picked.
Removing the relevant part in /etc/fonts/conf.d/65-google-droid-sans-fonts.conf
mitigates this issue. However since both Noto Sans & Droid Sans do not contain
CJK characters, they should both be skipped in favor of CJK fonts. Could this
be a metadata problem? i.e. Droid Sans wrongly advertises as CJK capable.
