[Bug 1784650] New: Fontconfig is slow, causing stuttering and freezing

https://bugzilla.redhat.com/show_bug.cgi?id=1784650 Bug ID: 1784650 Summary: Fontconfig is slow, causing stuttering and freezing Product: Fedora Version: 31 Status: NEW Component: fontconfig Severity: high Assignee: tagoh(a)redhat.com Reporter: bepvte+bugzilla(a)gmail.com QA Contact: extras-qa(a)fedoraproject.org CC: ajax(a)redhat.com, caillon+fedoraproject(a)gmail.com, fonts-bugs(a)lists.fedoraproject.org, gnome-sig(a)lists.fedoraproject.org, i18n-bugs(a)lists.fedoraproject.org, john.j5live(a)gmail.com, mclasen(a)redhat.com, pnemade(a)redhat.com, rhughes(a)redhat.com, rstrode(a)redhat.com, sandmann(a)redhat.com, tagoh(a)redhat.com 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. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug 1820166] New: Droid sans overrides my default CJK font

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.

[Bug 2013083] New: 31-cantarell.conf causes inconsistent font choice for numerals and symbols when the system locale is zh-*
by bugzilla＠redhat.com 20 Jan '22

https://bugzilla.redhat.com/show_bug.cgi?id=2013083 Bug ID: 2013083 Summary: 31-cantarell.conf causes inconsistent font choice for numerals and symbols when the system locale is zh-* Product: Fedora Version: 35 Status: NEW Component: abattis-cantarell-fonts Assignee: klember(a)redhat.com Reporter: vtq-gnome(a)outlook.com QA Contact: extras-qa(a)fedoraproject.org CC: cosimo.cecchi(a)gmail.com, fonts-bugs(a)lists.fedoraproject.org, klember(a)redhat.com, mark(a)net-c.com, me(a)fale.io, tagoh(a)redhat.com Target Milestone: --- Link ID: GNOME Gitlab GNOME/gnome-shell/-/issues/4683 Classification: Fedora Created attachment 1832054 --> https://bugzilla.redhat.com/attachment.cgi?id=1832054&action=edit Inconsistent font for numerals and symbols in Nautilus Description of problem: In Fedora Workstation, the GNOME desktop is using Cantarell as its main font. However, the following section in /etc/fonts/conf.d/31-cantarell.conf, which comes from Fedora's abattis-cantarell-fonts package, allows the font choice to be overridden: <match target="pattern"> <test qual="any" name="family"> <string>Cantarell</string> </test> <edit name="family" mode="assign" binding="weak"> <string>Cantarell</string> </edit> </match> $ env LANG=en_US.utf8 fc-match Cantarell Cantarell-Regular.otf: "Cantarell" "Regular" $ env LANG=zh_CN.utf8 fc-match Cantarell NotoSansCJK-Regular.ttc: "Noto Sans CJK SC" "Regular" GTK/Pango seems to select a font based on the language of the text, and the decision is affected by the context. When the text is only numerals and symbols it will assume the language from the locale. This kind of decisions seems to be reasonable too. So for example, Latin script will still be displayed with Cantarell. "1234567890" will be displayed with Noto Sans CJK while "1234567890 GNOME" will be displayed with Cantarell (see screenshot): $ env LANG=zh_CN.utf8 pango-view --markup -t '<span face="Cantarell" font_features="tnum" size="xx-large">1234567890</span>' $ env LANG=zh_CN.utf8 pango-view --markup -t '<span face="Cantarell" font_features="tnum" size="xx-large">1234567890 GNOME</span>' As a result, numerals and symbols in the GNOME UI are sometimes displayed with Cantarell and sometimes displayed with Noto Sans CJK (see screenshots). The inconsistency makes the UI appear broken. This is especially noticeable for time in various places of the UI, because time is displayed in Noto Sans CJK and the separator between hour and minute (a ratio symbol, which is a full-width glyth in Noto Sans CJK and many other CJK fonts) has extra blank space around it. (See https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/4683) Version-Release number of selected component (if applicable): 0.301-3.fc35 How reproducible: Always Steps to Reproduce: 1. In GNOME desktop, choose "中文臺灣", "中文香港", or "汉语中国" in "Settings" – "Region & Language" – "Language". 2. Log out & log in. Actual results: Numerals and symbols in the GNOME UI are sometimes displayed with Cantarell and sometimes displayed with Noto Sans CJK (see screenshots). Expected results: Numerals and symbols should be consistently displayed with the same font, ideally the same as the Latin alphabet. Since GNOME explicitly requests Cantarell as UI font, Cantarell should be used here. Noto Sans CJK would only be used as fallback for Chinese characters which are not covered by Cantarell. Note that other common Latin fonts in the system are not overridden by Noto Sans CJK like Cantarell is: $ env LANG=zh_CN.utf8 fc-match "DejaVu Sans" DejaVuSans.ttf: "DejaVu Sans" "Regular" $ env LANG=zh_CN.utf8 fc-match "Liberation Sans" LiberationSans-Regular.ttf: "Liberation Sans" "Regular" $ env LANG=zh_CN.utf8 fc-match "Nimbus Sans" NimbusSans-Regular.otf: "Nimbus Sans" "Regular" Generally in mixed use of Latin and Chinese fonts, it is common to use the selected Latin font for numbers and symbols and only fallback to the Chinese font for glyths not covered. This is seen in word processors (e.g. LibreOffice), Flatpak apps (because the Freedesktop runtime doesn't have font config similar to the 31-cantarell.conf), as well as other OS (e.g. MacOS, Android). By deleting the previously mentioned fontconfig section in 31-cantarell.conf, the expected results can be achieved (see screenshots). env LANG=zh_CN.utf8 fc-match Cantarell Cantarell-Regular.otf: "Cantarell" "Regular" Additional info: In my test without the relevant fontconfig section everything seems to be working very well and I've not noticed any adverse effect. But I'm not aware of why it was originally included in the package. An alternative solution is to use Noto Sans CJK for everything if the locale is zh-*. But this is less favorable because it's against upstream choice of Cantarell and needs a change in gsettings-desktop-schemas for these locales. The clock separator issue would additionally need workarounds in Nautilus and in GNOME translations to fix. -- You are receiving this mail because: You are on the CC list for the bug. https://bugzilla.redhat.com/show_bug.cgi?id=2013083
