When history swiping is enabled, there's visible UI stutter on my late-2012 top-end rMBP. Typically this manifests as two "steps" in the swipe before it becomes smooth.

This looks pretty bad, to the point that between the jank and Bug 836430, I'm turning the feature off!

(Alas, I would guess that quadrupling the size of the screenshot would make things worse...)
This might get fixed by bug 933389.

Wouldn't 939480 make this bug obsolete?
For moving the current page, yes, but we still need snapshots for the next + previous pages, and those have to be taken at some point preferably without janking.
