[Blocking Requested - why for this release]:

The uplifted patch cannot solve reported bug.
- https://hg.mozilla.org/releases/mozilla-aurora/rev/f78313ff6cbf

The bug still can be reproduced on v2.0.

Comment 2

[Kartikaya Gupta (email:[e-mail])]

Was this fixed on 2.0 and regressed again? Or did the original fix just never fix this on 2.0?

[Johan Lorenzo [:jlorenzo]]

I remember verifying bug 1022577 on aurora at the time. My bad, I didn't flip the corresponding flag and I didn't include the build details.

I've just rechecked this issue today. I flashed my Flame back when the issue was present[1], I am able to reproduce the issue. Then, I flashed it on a build that included the patch[2]: I can't reproduce.

Lancy, can you repro on build[2]?

Hi Johan,

There is no June ROM on our side, so I cannot help to repro this issue using the ROM you specify.

Hi, Johan,

My bad. We forgot to give Lancy the other base images.
Sorry for any inconvenience.

Hi, Lancy,

Sorry. It's a JB base image with 20140613160204 build.

Hi, Kartikaya and Johan,

Thanks for your suggestion and help.
This seems to be a regression since this bug cannot be reproduced on 20140613160204 build.
I would like to find the regression window.

Sorry for any inconvenience.
Have a nice weekend.

Hi, Lancy,

My bad. Please skip this request.

Do you know who is going to find the regression window here? I'm assuming this regression is specific to 2.0 and the bug is still fixed on all other codelines. Please correct me if I'm wrong.

Comment 9

[Pi Wei Cheng [:piwei] (inactive)]

We can help with finding the regression window, but first I needed to verify the information provided at comment 3 and comment 6 were true - that this bug used to not reproduce in 2.0/Aurora branch. And I've verified myself that the information is INCORRECT. I can reproduce this bug on the build that was claimed not reproducible.

Tested and issue reproduced in:
Device: Flame (JB, shallow flash)
BuildID: 20140613160204
Gaia: 5b1fdc6000d35962769e789b924b24e166a27759
Gecko: e161f3e3b332
Version: 32.0a2 (2.0 Aurora)
Firmware: V123
User Agent: Mozilla/5.0 (Mobile; rv:32.0) Gecko/32.0 Firefox/32.0

So no, there's NOT a regression within the 2.0/Aurora branch hence a regression window is NOT possible.

[Johan Lorenzo [:jlorenzo]]

Thanks for double checking Pi Wei! Was this bug harder to repro on the build you tried? Would you mind checking 2.1, 2.2 and master?

On the 20140613160204 build I was able to reproduce the bug 3/3.

I did check 2.1 to make sure it isn't reproducing and to see what it looks like on a build that doesn't reproduce the bug. (For regression windows we always verify that there's a clear difference between broken builds and working builds to ensure window accuracy)

To complete this NI I further checked 2.2 and 3.0 master and found no contradiction to the tracking flags.

Hi, Pi Wei,

Thanks for your help! :)

[Triage]

1. per above comments it seems a regression from 1.4, but not a regression for 2.0 itself. 
2. per video it doesn't looks like normal user behavior. (need fast scroll up/down homescreen)
3. also considering 2.0 timing and no partner ask for this.

So de-tag for 2.0 now.

Comment 14

[Kartikaya Gupta (email:[e-mail])]

Since this bug is restricted to an old codeline and people don't seem to be running into it, I'm going to close this bug as not worth the effort to fix. Feel free to reopen if this changes.

Bad user experience.
Nominate this bug since it is easy to reproduce on the next shipping device.
Add tag - "2.0m?"


Please minus this bug if pals don't think this is a high priority issue.
Many thanks.
