* SUMMARY The overlay scrollbars fail to appear sometimes… it is pretty reproducible, and has something to do with beginning a scroll while they scrollbars are fading out. * STEPS TO REPRODUCE 1. Using a build with overlay scrollbars, go to a website with a vertical scrollbar 2. Use trackpad to scroll 3. Briefly stop scrolling; leave your 2 fingers on the trackpad 4. When the scrollbars start to fade away, resume scrolling * RESULTS If you time it just right, the scrollbars won't re-appear. You can scroll just fine, there is just no visual scrollbar. <rdar://problem/8953779> Patch forthcoming.

Comment on attachment 86097 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=86097&action=review > Source/WebCore/platform/mac/ScrollAnimatorMac.mm:401 > + [[NSAnimationContext currentContext] setDuration:duration]; It’s a little weird that we have to pass the duration here and also to the animation.
