Bug 468336 – =media-libs/freetype-2.4.11-r2 - Breaks subpixel rendering in Firefox.

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description octoploid 2013-05-02 22:00:51 UTC]

Since I've installed freetype-2.4.11-r2 fonts aren't subpixel
rendered anymore in Firefox. Instead simple grayscale rendering is used.
See attached magnified screenshots.
Downgrading to freetype-2.4.11 fixes the issue.

Reproducible: Always

Hit enter too fast, just want to say I see this in other programs as well.

Re-assigning to multilib, since this seems a problem with the multilib ebuild only.

While you are at it, make sure to apply the locale patch as well.

Could you attach your /usr/include/freetype2/freetype/config/ftoption.h please? Which arch are you using?

[Comment 6 octoploid 2013-05-04 07:36:57 UTC]

Arch is x86_64.
ftoption.h is the same in 2.4.11-r2 and 2.4.11.
ftconfig.h differs however (/var/.snapshot/... is 2.4.11-r2):

Hmm, you can try syncing and rebuilding -r2, since I added the locale patch. Other than that, I don't see *how* it could fail.

I've just built -r0 and -r2, and 'diff -dupr' shows that the only diff is in the header, while libraries are identical. Is that the case for you as well?

Yes, the locale patch did the trick. Everything is fine again.
Thanks.
