950766 - [B2G][Window Management] wrapper UI incorrectly shows background when keyboard is shown

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::System::Window Mgmt, defect)

Description

[Matthew Vaughan]

Attachment: Screenshot of login screen with and without keyboard.

Description:
When attempting to sign into an app, such as Facebook, Twitter, Google+, etc., that has been saved to the Homescreen from E.me, the login screen for the apps can become incorrectly displayed after evoking the keyboard. The login screen will appear too short and expose a part of the Homescreen at the bottom of the screen. If the keyboard is on the screen, the part of the exposed Homescreen can be seen just above the keyboard. This issue will not appear until the user brings up the keyboard. From then on this issue will be present until the user reboots the device.

This issue does NOT occur when signing in via a website in the Browser. This issue does occur on some apps that were installed from the Marketplace (e.g. Facebook will repro this issue but Twitter will not).

Prerequisites:
Have an active WiFi or data connection.

Repro Steps:
1) Update Buri to Master M-C (1.4) BuildID: 20131216040201
2) Navigate to E.me screen
3) Tap on the Social collection
4) Save Facebook to the Homescreen
5) Back out to the Homescreen
6) Tap on Facebook
7) Attempt to sign in

Actual:
The login screen is displayed with a part of the Homescreen background visible at the bottom (just above the keyboard).

Expected:
The Homescreen cannot be seen in any way from the login screen with or without the keyboard.

In addition, the Homescreen background can be seen above the keyboard for just a moment when switching between the username text box and the password text box on a login screen for an app not saved to the Homescreen. Therefore, this can been seen when logging in anywhere such as in the Browser.
