User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:71.0) Gecko/20100101 Firefox/71.0
Steps to reproduce:
As from 71.0a1 (2019-10-02) (64-bit) some fonts appear blurry. See shots
Bad shots are from 71.0a1 (2019-10-02) (64-bit). Good ones are from yesterday build 71.0a1 (2019-10-01) (64-bit).
This is Gentoo Linux. Shots taken from the same machine and same time.

What does your fontconfig hint style setup look like in /etc/fonts/conf.d or similar? Also, what version of freetype are you using?
Fri Jul 5 22:33:46 2019 >>> media-libs/freetype-2.10.1
<match target="font">
<edit mode="assign" name="rgba"><const>rgb</const></edit>
<edit mode="assign" name="hinting"><bool>true</bool></edit>
<edit mode="assign" name="hintstyle"><const>hintfull</const></edit>
<edit mode="assign" name="antialias"><bool>true</bool></edit>
<edit mode="assign" name="lcdfilter"><const>lcddefault</const></edit>
</match>
BUT, I don't change anything about fonts. Just update firefox. Also if I go back to "good" version of firefox fonts are back to normal.

Bug 1585931 - don't use subpixel positioning for Fontconfig fonts if full hinting is requested. r?jfkthame
Beta/Release Uplift Approval Request
- User impact if declined: Regression on Linux where users who have explicitly forced Fontconfig hinting of text will not get the requested hinting. Just missed the cut-off for getting this change in 71...
- Is this code covered by automated tests?: Yes
- Has the fix been verified in Nightly?: No
- Needs manual test from QE?: No
- If yes, steps to reproduce:
- List of other uplifts needed: None
- Risk to taking this patch: Low
- Why is the change risky/not risky? (and alternatives if risky): In 71, subpixel positioning was enabled for text on Linux. This change just disables subpixel positioning again for users who have forced hinting of text, effectively just putting things back the way they used to be for those users.
- String changes made/needed:

At least for me, fonts looks much better now. Not sure if they back what were before, but they are not blurry or uneven.

Hi drjeckyll, if you would be so kind, can you verify that the fix is working for you on Firefox Beta 71.0b5 (https://archive.mozilla.org/pub/firefox/candidates/71.0b5-candidates/build1/) unfortunately we could not reproduce this issue on our hardware.
Thank you!
