Description: Scrolling functionality frequently freezes while in Settings. The issue is recoverable by killing the app and then relaunching, but since it happens quite often i thought it would better be investigated. Repro Steps: 1) Updated Buri to BuildID: 20131120040202 2) Open Setting app 3) Scroll up/down Actual: Unable to scroll, have to close app and relaunch to restore scrolling Expected: Able to scroll every time when opening app Environmental Variables: Device: Buri v1.3 M-C BuildID: 20131120040202 Gaia: c26480b22ce28c812c347290dd4bad090d83db6f Gecko: 4f993fa378eb Version: 28.0a1 Firmware Version: V1.2_20131115 Notes: the behavior also has been observed while in Terra app Repro frequency: 40% See attached logcat, though I doubt there is anything in the logcat...
within the logcat: 11-20 17:39:29.639: E/memalloc(136): /dev/pmem: No more pmem available 11-20 17:39:29.639: W/memalloc(136): Falling back to ashmem 11-20 17:39:29.699: E/msm7627a.hwcomposer(136): hwc_set: Unable to render by hwc due to non-pmem memory 11-20 17:39:29.709: D/HwcUtils(136): Skip layer

It might be great if we could have a video of the symptom. From Comment 1, it is not easy to understand the how ui was freezed.

this is a regression, the issue does not reproduce on yesterdays build: BuildID: 20131119040204 Gaia: 4ecbc106a3fcf72cbd6dd8a43c46de7bacbedf20 Gecko: ba9ecdea3a90 Version: 28.0a1 Firmware Version: V1.2_20131115 Sotaro, i can record a video for you but actually it's just a screen that i cannot scroll :), open Settings app and cannot scroll up or down...

does not reproduce on 1.2 video of the issue - http://youtu.be/9bRtJxffeaY
Keywords: qawanted
The video does see what I was seeing as well when I was doing some testing around this. I think when : 11-20 17:39:29.709: D/HwcUtils(136): Skip layer occurs, you cannot pan. I noticed quite a lot of the skip layer when looking at the logs and seeing this issue occur. bug 907463 had landed within that regression window. I am not sure if this is the cause of the issue as of yet.

I also explained in https://bugzilla.mozilla.org/show_bug.cgi?id=942701#c9 ---- So it seems like the preallocated process is lying. The check at http://mxr.mozilla.org/mozilla-central/source/dom/browser-element/BrowserElementPanning.js#51 fails because the app says that docShell.asyncPanZoomEnabled == true while we are in the preallocated process. When the prealocatted process is consume by a real app, this value is correct but it is too late. I seems like something has changed in the way we initialize the asyncPanZoomEnabled value by default. ---- I'm not sure this is the issue here, but since the other bug has been resolved as a duplicate of this one.

Just like what Jason said. Actually, I don't think it's related to DSDS...

I see Jason asking for a regression range, is the regression range in comment 5 valid?

(In reply to Jason Smith [:jsmith] from comment #20) > So can we close this as works for me then? I would say so. I've also asked testers around, the issue no longer happens to us (we have 20 testers in the room :)), so can be closed.
