Bug ID: 1469712
Summary: font antialiasing/hinting is not working on Fedora 26
Product: Fedora
Version: 26
Component: freetype
Severity: high
Assignee: mkasik(a)redhat.com
Reporter: mchehab(a)infradead.org
QA Contact: extras-qa(a)fedoraproject.org
CC: behdad(a)fedoraproject.org,

Description of problem:
After upgrading from Fedora 25 to Fedora 26, font hinting doesn't work anymore.
All fonts look really ugly on my 32' monitor, and changing font antialias/hint
options at Gnome, Plasma or Mate doesn't produce any visible changes anymore.
With Fedora 25, I used freetype-freeword from rpmfusion, as it produced a
better result than the default freetype font hinting (although both work). On
Fedora 26, neither with or without freetype-freeword I can adjust font
hint/antialias anymore, as those options don't work anymore.
Version-Release number of selected component (if applicable):
freetype-2.7.1-9.fc26.x86_64

Hi,
could you attach here a screenshot of the issue in e.g. gedit or gtk3-demo? Do
you see this behaviour with some specific font?

Sounds like a similar problem I have after a fresh installation from Fedora 25
to 26 (Workstation edition, official release with all recent updates). I'm
using a copy of the font files for "Arial" and "Courier New" from an
original
MS Windows system. Both fonts look very pretty even *without* Anti-Aliasing,
which can useful on screens with < 2K resolution.
"Arial" is specifically designed to look excellent with and without
Anti-Aliasing. It's for a reason why this font is so popular. :-)
Starting with Fedora 26, "Arial" (and Courier New) looks ugly without
Anti-Aliasing (like most non-bitmap fonts do for years). It still looks okay
with Anti-Aliasing enabled.
I've tried with "gnome-tweak-tool" and also with
~/.config/fontconfig/fonts.conf, but "Arial" won't look pretty without
Anti-Aliasing.
There seems to be something broken with font rendering in Fedora 26.

I had the same problem.
This solution worked for me on Fedora 26:
echo export FREETYPE_PROPERTIES=\"truetype:interpreter-version=35\" | sudo tee
-a /etc/profile.d/freetype2.sh

Great hint! That seems to work really fine for most applications including GTK
(Menus, Titles, other texts), Firefox and Thunderbird (that's were I personally
use non-antialiased "Arial" the most).
However, now with Arial defined to be non-antialiased again (like I did in
Fedora 25 and before), suddenly Google Chrome totally freaks out. (It worked
fine in previous Fedora releases.)
For unknown reasons Chrome seems to disable "hinting" as soon as a font is
non-antialiased. The very same menus and other texts that look fine in Firefox,
they are basically unreadable in Chrome. It doesn't matter if/how
FREETYPE_PROPERTIES is set, Chrome seems to ignore it completely. Maybe Chrome
cannot handle the new version of the freetype library.
(Even with Anti-Aliasing turned off, Hinting is still essential to have nicely
rendered fonts.)
The problem is that a lot of web sites use "Arial" as default font, so it must
look good in Firefox and Chrome. (Even for systems with Arial installed, same
applies for the replacement font... it must look good in both browsers.)
In Fedora 25 and before Chrome basically ignored fontconfig. Even if I
configured "Arial" to be non-antialiased, Chrome displayed it antialiased. That
was okay. I rarely use Chrome, and I could live with antialiased Arial in
Chrome if at least the hinting worked. In Fedora 26 Chrome now respects the
non-antialiased configuration but fails with the hinting.

Font hinting sample F25 and F26
I have the same problem. Setting FREETYPE_PROPERTIES as advised in comment #3
*does* help.
It would be nice though if this worked out-of-the-box. Attaching a screenshot
of the *default* behaviour (i.e. *without* setting FREETYPE_PROPERTIES).

This is the same problem as in the bug #1470509. Freetype has changed default
hinting engine in 2.7 from v35 to v40. The change is more apparent when the
antialiasing is off. You can reproduce it in e.g. ftview by running "ftview -m
"This is a test text" 19 /usr/share/fonts/dejavu/DejaVuSansMono.ttf",
turning
off antialiasing by pressing "a" and then you can switch between the hinting
modes by pressing "H".
Upstream won't change it back and so we won't too.
If you prefer the older hinting engine, you can select it by setting
environment variable "FREETYPE_PROPERTIES" to
"truetype:interpreter-version=35"
in e.g. ~/.bash_profile.
I'm closing this as notabug since the change is intentional (and looking at the
freetype mailing list, they know about the visual change, also see
https://www.freetype.org/freetype2/docs/subpixel-hinting.html for more info
about the engine).

Market: This bug is not about different appearance - but about subpixel
antialising not working anymore (please see the screenshot attached - taken
from the xfce font settiongs dialog).
I can't imagine that loosing subpixel hinting is intentional.

Update: In my case I had to install freetype-freeworld to get RGB /
subpixel-antialiasing to work again. It has absolutly *nothing* to do with the
truetype interpreter version as mentioned my Marek.

(In reply to Clemens Eisserer from comment #7)
Marek: This bug is not about different appearance - but about
subpixel
antialising not working anymore (please see the screenshot attached - taken
from the xfce font settiongs dialog).
Actually, original reporter did not respond to my questions and did not provide
a screenshot so we really don't know about what this bug is about. But it
seemed to describe the change which happened in hinting.
It would be better if you could open a separate bug for your issue so I can
evaluate it properly (so I see which version of OS and freetype you use).
