The following two tests: imported/w3c/web-platform-tests/css/css-multicol/multicol-rule-fraction-003.xht [ ImageOnlyFailure ] imported/w3c/web-platform-tests/css/css-multicol/multicol-rule-shorthand-2.xht [ ImageOnlyFailure ] were failing on platform GTK before

because we were antialiasing Ahem. However, after disabling antialiasing for the Ahem font in
bug 204671
they continue to fail. Looking at the visual diff, it pretty much appears we are still antialiasing Ahem for this two tests. Its unclear why it happens, but it looks something related in the way we run this tests in our runner As I can't reproduce the failure running the tests with the WPT runner. I can't also reproduce the antialiasing issue in the MiniBrowser, only seems to happen with WTR.

This seems to be caused because we are disabling gtk-xft-hinting in WTR.

Seems I got confused with this. Enabling hinting was workarounding the issue maybe. The underlying cause was that this two tests loaded the Ahem font as a webfont, and that was not working when i tested this on a previous version of the patch from
