Initial investigation: There seems to be a blocking of task by blink scheduler because of prioritization of other task. So this may be result of side effect of blink scheduler policy. Need to check more before any conclusion. I get this log on console thrown by blink scheduler while scrolling on slashdot.org
qml: [JS] (https://slashdot.org/:0) Blink deferred a task in order to make scrolling smoother. Your timer and network tasks should take less than 50ms to run to avoid this.

The page doesn't move for a short time then scrolls super fast almost to the bottom. Seems like the scroll events are getting queued up and then all applied at once. This site reproduces it pretty easy for me: 1) goto boston.craigslist.org 2) type "kayak" in the search field 3) you'll get a page full of results 4) click on one of the results 5) wait till page fully loads, flick quickly a few times, first flicks ignored. then press back button 6) wait till page fully loads and then start scrolling (flicking up, multiple times), first flicks ignored/queued then scrolling happens fast Expected results: the page should start scrolling immediately and keep up with action of finger Actual results: the page is not responsive for a few seconds then scrolls super fast toward the bottom To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1584965/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
