If I fling this page there will be a noticeable pause near the end of the fling and then the fling will continue. This suggests that the compositor is being blocked for a significant amount of time for some reason. (Perhaps tile allocation?)

Can't repro on my OS X nightly. There's a bunch of nested scrollables on this page. Are you flinging the top-level page only? Assuming the issue isn't handoff-related, it would be good to grab a profile so we can see what's going on.

I can reproduce with my cursor outside of the nested scrollables. I can try to grab a profile somehow.

Here's the profile. http://people.mozilla.org/~bgirard/cleopatra/#report=5e8ca305c6f03eab6ad12fa16c25bba094a7329f We're spending large amount of time doing texture uploads and allocations. I suspect we're asking to upload too much at once and I expect we're churning texture for some reason.
