Two places said the history cushion's evidence was a swipe that moved nothing for 689ms. That reading came from `ui-trace show` on a row taller than the viewport, which reports clipped bounds and so prints "nothing moved" for a list that is scrolling fine -- and it was taken on the software renderer besides. The finding it supported is sound and has a better witness: counted at the server, ten swipes asked for ten pages before the change and three after, which does not depend on how anything renders. Also records what the screen actually costs now, measured on the GPU emulator: 5.2-5.9% janky frames and 0-2 slow UI-thread frames flinging fast, against 3.3% for the stock Settings app on the same device. With the note that matters for repeating it -- let the screen settle before resetting gfxinfo, because the first seconds after opening a session are every row being composed for the first time and read three times worse.
