This site goes blank as soon as you touch scroll. With wheel scroll it inches along at a reduced rate. http://www.socialfly.com.br/videos/11-este-homem-resolve-deixar-a-baboseira-de-lado-e-resume-o-maior-do-problema-do-brasil-em-2-minutos
I see one display port update and then phhbt - nothing after that. APZC: Calculated displayport as (0.000000 -18.633333 1376.000000 2093.066650) from velocity (0.000000 0.031250) acceleration (1.000000 1.000000) paint time 0.000000 metrics: i=(7 3) cb=(0 0 1920 1080) dp=(0.000 -3.583 1376.000 2093.067) v=(0.000 0.000 1376.000 774.000) s=(0.000 18.633) sr=(0.000 0.000 1376.000 2093.067) z=(1.395 1.000 1.000 1.395) 0 Input is still arriving at the apzc, but it doesn't appear to be doing anything with it.
mState appears to be set correctly as well for the drag.
Reduced test case. If I remove the float: left on div#bug_bug_bug it touch scrolls fine. The site also mysteriously doesn't pinch zoom. There's no viewport meta tag or @viewport css rule.
I'm unable to reproduce some of the issues you describe, either on the bug URL or the reduced test case. On both pages I can touch-scroll fine. On the socialfly page there is a big checkerboard-type flash right when I start scrolling which is pretty ugly but once the scrolling gets going it seems to behave ok. On the reduced case I can't pinch zoom - I can look into that if needed but it doesn't seem like as serious of an issue. Can you guys re-check on the latest m-c code if you're still seeing the problems or not?
Things seem to have improved a bit on that page. I'll check aurora as well. The first drag doesn't seem to work. but subsequent drags do now.
Same behavior on aurora. First drag is wonky, subsequent drags seems to work.
Summary: site goes blank when scrolled → first scroll and pinch-zooming don't work on specific site
Metro-specific bug so I'm closing it out. We can reopen it or file a new one if metro ever gets resurrected.
