STR: 1. Load http://trollitc.com/2012/06/catan-junior-in-review-or-go-out-and-get-this-game-it-rocks/ 2. Scroll down the long page AR: Scrolling is very janky. Even when slow scrolling, the page will pause for 1/4 second every 1/2 screen or so. ER: This long page scrolls more smoothly (but is not perfect) in Chrome and ICS stock browser.
I profiled this page and uploaded the profile to http://people.mozilla.com/~bgirard/cleopatra/?report=e6613622a95d7330da14e5f7a78a268c3c1eebfc - some symbols are missing but it appears that drawing backgrounds and borders is causing the jankiness.
(In reply to Kartikaya Gupta (:kats) from comment #1) > but it appears that drawing backgrounds and borders is causing the jankiness. Uh, ignore that. With paintflashing turned on, I can see large parts of the page are getting repainted on scrolling, so the large uploads are inducing jank.
No jank or paintflashing on latest nightly on a nexus 4.
