When visiting youtube.com, if the user makes a video fullscreen then returns to in-browser view, the homescreen becomes visible and cuts off half the browser.

Repro Steps:
1. Update Buri 1.3 device to buildID: 20131104044747.
2. Access www.youtube.com > play any video > tap fullscreen.
3. Return to in-browser from fullscreen view.

Actual Results:
Browser becomes cutoff and the homescreen is displayed.

Expected Results:
Browser remains fully rendered at all times.

Repro Rate: 3/6 50%

I'm doubtful this is a browser bug - probably more likely a system bug.

Lucas, can you supply two things please?  The adb shell logcat as well as the adb shell dmesg?

I wonder if this has to do with bug 905882/bug 923303?

I'm doubtful this is related to those two bugs. This is likely a regression from the window management refactoring work going on.

The similar issue is noticed on the latest build with different steps.

1) Open "Browser" app from the home screen
2) Rotate the device to landscape mode
3) Press the "Home" button in the landscape mode to return to the home screen
4) Rotate the device to portrait view and open the "Browser"

Actual result:
The Browser reveals only half screen

Expected result:
The browser opens in the full page view

1. go to youtube
2. play a video
3. go to landscape
4. go to portrait.

This will cause the bug as well.

I was able to reproduce this issue when APZ was turned on for the Video app.  It's an APZ issue.

I don't think this is related to the meta viewport work going on in that bug.

This reproduces without the APZ pieces turned on.

Comment 11

[Jason Smith [:jsmith]]

Removing the dependency here because this was filed in the browser app content, which is not related to the work going on for turning on APZC across Gaia.

I agree that it does not have to do with : bug 905882/bug 923303.
I should have stated that APZ makes it easier to see.

I still think it does have to do with not having a meta viewport:
https://developer.mozilla.org/en-US/docs/Mozilla/Mobile/Viewport_meta_tag
see first image.  Things will get cut off/mishappen in the content size without meta viewports.

I don't think so - the screenshot involves bleeding across different apps, which usually is a bug involving window management in Gaia.

QA Wanted - Is this still reproducible? There was a patch that landed recently that should have fixed this.
