Re: [SOLVED] fontconfig 2.11.94 slows down programs startup

fontconfig-2.11.95 left testing, problem's gone -- but all non-bitmap fonts look different now. *sigh* ... which is caused by the new "10-hinting-slight.conf" being active by default. I'll be putting this in my ~/.config/fontconfig/fonts.conf and I'm back to "normal":

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
	<!-- Disable the effects of 10-hinting-slight.conf -->
	<match target="pattern">
		<edit name="hintstyle" mode="delete"><const>hintslight</const></edit>
	</match>
</fontconfig>

Nice job!  This works for me as well.
I usually like to understand what the fix actually does so as not to use it blindly.
I see the docs here.
And changelog here; commit 98434b3392172233094cac25ade7225c93da9f1c
Did I miss anything?

Two different issues are discussed in this thread:
d179cbc2536af16cf0f4992e0a4b2d751437ee6c fixes the slowness
98434b3392172233094cac25ade7225c93da9f1c blindly makes hintslight the default for every font, even bitmap ones(if i understood properly)

Both were pushed in the 2.11.95 release.

Relax, it's *only* a default (and it's actually one of the first rules I use, before e.g. font-family-specific tweaking). Feel free to use numbers 11-99 for fontconfig configuration files, to tweak fontconfig to your liking.

The syntax should actually be the following:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
        <!-- Disable the effects of 10-hinting-slight.conf -->
        <match target="font">
                <test name="hintstyle" compare="eq">
                        <const>hintslight</const>
                </test>
                <edit name="hintstyle" mode="delete"/>
        </match>
</fontconfig>

Yes, yes, i'm completely relaxed, i don't even use any bitmap font atm.
But from what i understand about hinting, it should never be used for bitmap font rendering; maybe is freetype that should ignore that "hint" in that case (?)

There's multiple hints to consider, especially whether any hinting at all is applied

E.g. my defaults:

    <match target="font">
        <edit mode="assign" name="rgba"><const>rgb</const></edit>
        <edit mode="assign" name="autohint"><bool>true</bool></edit>
        <edit mode="assign" name="hintstyle"><const>hintslight</const></edit>
        <edit mode="assign" name="hinting"><bool>true</bool></edit>
        <edit mode="assign" name="antialias"><bool>true</bool></edit>
        <edit mode="assign" name="lcdfilter"><const>lcddefault</const></edit>
    </match>

(I don't use bitmap fonts, because I'm not a masochist.)

Re: [SOLVED] fontconfig 2.11.94 slows down programs startup

The temporary workaround I found to this problem was to remove libbluray and install libbluray-git.  Not ideal, but doing so allowed me to forego installing freetype2 and keep freetype2-ubuntu and fontconfig-ubuntu installed.

That is completely unrelated, and a really silly workaround.

My bad. I posted on the wrong thread. It was late. Meant to post that response here. Fixed now.
