--- Comment #1 from Carlos Alberto Lopez Perez <clopez at igalia.com> ---
It seems the rAF timer in WebCore defaults to ~66FPS (15 ms) after r94908. See rationale: https://bugs.webkit.org/show_bug.cgi?id=67171#c12

But the Mac/iOS port implements REQUEST_ANIMATION_FRAME_DISPLAY_MONITOR ( see bug 68911 ) which allows to sync and throttle the rAF timer according to the display refresh rate.
