It is still possible to fire paint-related LayoutMilestones before CA has committed the changes. To ensure we wait for the commit, we should wait until the end of the runloop with a zero-delay timer. <rdar://problem/13822315>

Comment on attachment 200971 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=200971&action=review > Source/WebCore/rendering/RenderLayerCompositor.cpp:377 > + if (!m_paintRelatedMilestonesTimer.isActive()) > + m_paintRelatedMilestonesTimer.startOneShot(0); This made it so that _every_ layer flush we start a timer, which most of the time does nothing :(
