[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.

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. -- 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

https://bugzilla.redhat.com/show_bug.cgi?id=1820166 Bug ID: 1820166 Summary: Droid sans overrides my default CJK font Product: Fedora Version: 32 Status: NEW Component: google-droid-fonts Severity: low Assignee: nicolas.mailhot(a)laposte.net Reporter: taocrismon(a)hotmail.com QA Contact: extras-qa(a)fedoraproject.org CC: fonts-bugs(a)lists.fedoraproject.org, nicolas.mailhot(a)laposte.net, oliver(a)redhat.com, paul(a)frixxon.co.uk, tremble(a)tremble.org.uk 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.

With recent update the text in Firefox and Thunderbird gained weird padding, causing wasted space, weird alignment issues, sometimes slight text cut-off at bottom (Thunderbird). Version-Release number of selected component (if applicable): google-droid-sans-fonts-20200215-3.fc32.noarch Last good: google-droid-sans-fonts-20120715-16.fc31.noarch How reproducible: Set Droid Sans 11 (also different size) as a GUI font. See how menus and parts of GUI looks like, overlaps and behaves. Compare by testing old version of the package, or different font such as Roboto. Steps to Reproduce: 1. Install google-droid-sans-fonts-20200215-3.fc32.noarch 2. Set Droid Sans 11 as default a GUI font 3. Open Thunderbird or Firefox Actual results: Weird unnecesarry padding in menus, cut-offs and similar text issues. Expected results: No change when compared to old version. Additional info: Reproducible in clean XFCE spin VM. Easily fixed by using similar font (Roboto) or old version of the package, so the problem is in the font package. -- You are receiving this mail because: You are on the CC list for the bug.
