Description Alexey Proskuryakov 2018-02-25 12:01:04 PST
WebProcess::initializeWebProcess() can only enable font smoothing, never disable it - but it's enabled by default in WebCore.

This manifests in sporadic font rendering related failures on WebKit tests, as the first test that runs after killing a frozen WebContent doesn't get font smoothing disabled.
