Description

[Viorela Ioia [:viorela]]

Attachment: logcat.txt

While runnging test_marketplace_search_and_install_app.py, I noticed that sometimes the bottom half of the screen gets black. I wasn't able to reproduce it manually. 
I attached the logcat of the issue, and also a screenshot. 

STR: 
1. Launch marketplace dev
2. Type the name of the first app that appears in the Popular section, by using marionette send_keys method
3. Wait for the apps list to be displayed

Expected results: 
The app list is displayed

Actual results:
The app list is diplayed, but half of the screen gets black.

Botond - Is this potentially related or a dupe of bug 966282?

Can you verify that the base build is using v1.2-device.cfg please?  It looks like it potentially could be from the base build issue.

The symptoms suggest it is unrelated.

This issue is also occurring on the latest Buri v 1.4.0 Mozilla RIL

It is not just the bottom of the screen that is turning black when scrolling the marketplace. Sometimes there is a black square that appears where "All categories" is located and other times it appears in the middle of the screen.

Okay - comment 5 says we have STR on a prod device. Can we give the explicit STR here for the prod device reproduction?

Comment 7

[Cody Roesch [:croesch]]

I've been able to reproduce this 4/4 times today doing the following steps on v1.4.

1. Have wifi and data enabled on the Buri device.
2. Launch Marketplace and wait for it to load.
3. Scroll through the market place.
4. Turn off wifi then close out of the marketplace completely.
5. Relaunch marketplace and scroll while only using data connection.
6. You should now see the black boxes from the marketplace loading screen background if you scroll up and down in the marketplace.

I'm not sure why these are the steps that work. I've tried to just load the marketplace in the first place using just Data but was not able to get the bug to happen.

[Jason Smith [:jsmith]]

Okay - with the STR in comment 7, can you check what happens on 1.3?

Comment 9

[Cody Roesch [:croesch]]

Hi Jason,
   I'm unable to get this bug to occur on v1.3. Out of 4 attempts I never saw any black boxes while scrolling with Data only as described in step 6. I get typical loading behavior.

Sounds like we've got a regression on trunk then.

[Milan Sreckovic [:milan] (needinfo for best results)]

Martijn, if you have a chance, can you figure out the regression window?

If you need a regression window here faster than normal, then please flag me down with the request. I'll redirect this to Sarah, as she's the lead on handling QA requests.

Assigning James as QA Contact for this bug.

Thanks.  Yes, need the regression window faster than normal.  Thanks.

[Jason Smith [:jsmith]]

Sarah mentioned in IRC that there's inconsistent results using the above STR, so I'm switching this to steps-wanted to nail down the STR.

Comment 16

[J Zimbrick]

We've been able to reproduce this issue on 1.4, but it seems very inconsistent.

STR:
1. Connect the device to a slower data connection. (We used Buri devices connected to Edge.)
2. Open the Marketplace and let it load.
3. Scroll through the Marketplace.
4. The issue will happen sometimes while scrolling at this point.

The rate seems fairly low, something around 5% or so.

Comment 17

[Jason Smith [:jsmith]]

I'm dropping the blocking nom here because the repro rate is really low. The original bug reproduced on 1.3, so I'm not sure if this is a regression or not.

Comment 18

[Viorela Ioia [:viorela]]

I didn't see this issue for some time now. 
I ran test_marketplace_search_and_install_app.py several times locally and the issue is not reproducible.
I will close the bug, as it works for me.
