https://bugs.documentfoundation.org/show_bug.cgi?id=158366 --- Comment #36 from Martin Dauskardt --- I can confirm that with libcairo 1.16 the problem disappeared! My way with Xubuntu 23.10: sudo apt-get build-dep libcairo2 download https://gitlab.freedesktop.org/cairo/cairo/-/archive/1.16/cairo-1.16.zip cd cairo-1.16 ./autogen.sh ./configure --prefix=/usr/local sudo make install sudo ldconfig After a reboot the fonts are fine.

https://bugs.documentfoundation.org/show_bug.cgi?id=158366 --- Comment #34 from Camaleón --- Just adding more information on this. To recap, after digging a bit more, the current situation is: - Computer 1. Debian testing / Cairo 1.18 / LibreOffice 24.2 (bad font render) / LibreOffice 7.6 (bad font render) - Computer 2. Debian stable / Cairo 1.16 / LibreOffice 24.2 (good font render) / LibreOffice 7.6 (good font render) So, IIRC, in Computer 1 _there was a time_ LO was rendering fonts fine, until I installed 24.2 (devel) where this issue with fonts hinting started. But in the meantime, Computer 1 it also upgraded the Cairo version (from 1.16 to 1.18) as logs shows: testing@netbook:~/Escritorio$ zgrep libcairo2 /var/log/dpkg.log.* | grep -i upgrade /var/log/dpkg.log.1:2024-01-13 09:19:31 upgrade libcairo2:amd64 1.18.0-1 1.18.0-1+b1 /var/log/dpkg.log.5.gz:2023-09-16 09:44:42 upgrade libcairo2:amd64 1.16.0-7 1.17.8-3 /var/log/dpkg.log.5.gz:2023-09-30 11:41:57 upgrade libcairo2:amd64 1.17.8-3 1.18.0-1 Et voilà, it was _not just LO_ what was updated but also Cairo library (I must sorry because I was not aware of this) which seems to trigger the LO font rendering problem when anti aliasing is disabled system wide. So the question is now: - What kind of change has been implemented in Cairo that makes LO render fonts so badly when anti-aliasing is turned off? And how can it be avoided and return LO its fine and crispy font strokes? - Why other programs (eg., XFCE itself, Firefox, Thunderbird...) seem unaffected to the Cairo change? -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=158366 --- Comment #33 from Camaleón --- 1. As per the Cairo version installed on the system where I'm facing the issues with text hinting, it seems to be now at «1.18» on my current Debian testing: testing@netbook:~/linux-64-7.5$ dpkg -l | grep -i cairo ii gtk2-engines-murrine:amd64 0.98.2-3+b1 amd64 cairo-based gtk+-2.0 theme engine ii libcairo-gobject2:amd64 1.18.0-1+b1 amd64 Cairo 2D vector graphics library (GObject library) ii libcairo2:amd64 1.18.0-1+b1 amd64Cairo 2D vector graphics library ii libcairomm-1.0-1v5:amd64 1.14.5-1 amd64C++ wrappers for Cairo (shared libraries) ii libpangocairo-1.0-0:amd64 1.51.0+ds-4 amd64 Layout and rendering of internationalized text ii libpixman-1-0:amd64 0.42.2-1 amd64 pixel-manipulation library for X and cairo ii python3-cairo 1.25.1-2 amd64Python3 bindings for the Cairo vector graphics library ii python3-gi-cairo 3.46.0-3 2. As per bibisecting, I already tried with these set of repositories and just 7.4 had a good version of the font: bibisect-linux-64-7.4 Xisco Fauli core commit 436f14c2 ← this worked bibisect-linux-64-7.5 Xisco Fauli core commit c94961c6 ← none worked bibisect-linux-64-7.6 Xisco Fauli core commit 1c629ca0 ← none worked bibisect-linux-64-24.2 Xisco Fauli core commit 6f227b0d ← none worked Should I try another one? If so, what would be the best to try? I'm not very fluent when it comes to Git terminology and usage. 3. On my current Debian testing, neither XFCE nor other programs experience issues with font rendering, just LibreOffice display bad strokes. -- You are receiving this mail because: You are the assignee for the bug.

It is not present in editor mousepad or wordpad (wine). Whatever it is, it can't be a library or setting which is exclusively used by Libreoffice.

https://bugs.documentfoundation.org/show_bug.cgi?id=158366 --- Comment #29 from Camaleón --- Setting the environment variable «SAL_ALLOW_DEFAULT_HINTING=1» seems making no difference on my side when I run my usual LO 24.8.0.0.alpha0. The font hinting is still visually badly rendered. Maybe this is something related to this¹, but not sure how to get a «good» font rendering on my side (upwards 24.x LO releases) and this issue prevents me from upgrading. ¹How/where is font hinting performed in libreoffice? https://lists.freedesktop.org/archives/libreoffice/2023-November/091183.html -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=158366 --- Comment #28 from Caolán McNamara --- 7.6.4 is reported as good, but 7.6.4 includes the commit in the apparent bisect: https://cgit.freedesktop.org/libreoffice/core/commit/?h=libreoffice-7-6-4=bb495c6a2f00346698a041bce69a5a97effc79d7 so if 7.6.4 is good and 24.2 is not, then it's not just the presence of that commit that matters. That said, document text in writer, calc, impress etc is not rendered with the exact same settings as text in widgets/menus etc. See the presentation at https://events.documentfoundation.org/libreoffice-conference-2022/talk/B87ZBP/ for the details there. But all of that is already in 7.6 IIRC. By guess is that our different settings for rendering document text triggers some bug in whatever is the combination of cairo+freetype+etc on that system. It should be the case that the gen backend menu/widget text is rendered with the same settings as the system suggests, unlike the document text which can differ a little, and the a in Table etc already looks a little rubbish (while the doc text looks very rubbish) so I feel its more than just the resolution independent stuff at play here. It might be that: export SAL_ALLOW_DEFAULT_HINTING=1 makes a difference (but I don't recommend that variable as it given known broken behavior) -- You are receiving this mail because: You are the assignee for the bug.
