[Webkit-unassigned] [Bug 186280] Hiding many elements with opacity:0 is slower than hiding with visibility:hidden

--- Comment #1 from Simon Fraser (smfr) <simon.fraser at apple.com> ---
It looks like we spend more time in RenderLayer::updateLayerPositionsAfterLayout() with opacity, presumably because we have a large RenderLayer tree and don’t short-circuit that part. With visibility:hidden we probably have a smaller layer tree.
