Hi,
I originally posted this into bugzilla [1] and onto mono bug tracker
[2], but we were unable to solve the problem. Given that F33 is going
EOL soon and I will have to choose between losing my test case or
running without updates, I decided to post here.
In brief, since upgrading to F34, mono fonts look blurry (see
attached). I was now able
to reproduce it with my own app [3] which can be compiled with
xbuild MonoFontsTest.sln /p:TargetFrameworkVersion="v4.7.1"
It appears as if hinting is no longer working in the F34 and F35. I
tried disabling harfbuzz as this landed in F34 but it did not help.
Any ideas what is going on? Were there any fontconfig or other changes
in F34? Thank you for your help in advance.
Best regards,
Julian

I tried rebuilding F33 fontconfig on F35 and downgrading, it did not
help unfortunately.
Best regards,

It turns out that the blurriness was caused by cairo. Rebuilding
1.16.0-9 and downgrading to it restores the sharp fonts. Is this a bug
in mono? There is a somewhat related gtk4 bug, which says it it a feature:
https://gitlab.gnome.org/GNOME/gtk/-/issues/3787
Best regards,
Julian
