Joe Bowser commented on CB-6375:
--------------------------------
This is a WebView rendering issue, since the moment you tap on the screen, the
UI snaps back to where it should be.
Steps to reproduce:
1. Make sure the app isn't running, if it's running, it won't do this
2. Start the app
3. Tap on the text field to bring this to focus
4. Dismiss the keyboard
Expected:
The screen should return back to where it's supposed to be
What happens:
The screen scrolls below, showing an unrendered gap.
> When keyboard is dismissed. Page has a large gap at top of screen

> Key: CB-6375
> URL: https://issues.apache.org/jira/browse/CB-6375
> Project: Apache Cordova
> Issue Type: Bug
> Components: Android
> Affects Versions: 3.4.0
> Environment: Android 4.4.2 Nexus 5, jQuery Mobile 1.4.2, PhoneGap 3.4
> Reporter: Jonathan Yong
> Priority: Minor
>
> See screenshot here: http://imgur.com/NtQ4QSl
> Notice the large white gap at the top of the page
> When a page is tall enough to cause the page to slide upwards when the
> virtual keyboard is displayed, and while the page scroll position is scrolled
> down so that the header and / or other controls are hidden above the top edge
> of the screen, dismissing the keyboard will intermittently cause a page
> rendering error such that there is a large white gap above the header of the
> page, essentially pushing down all page contents.
> This also causes the hitboxes of buttons and other form controls to differ
> from the on screen view i.e. the hitboxes are where the controls should have
> appeared had there not been a large gap at the top of the screen.
> This gap is present on all pages within the app and will remain until another
> text input field is focused and the keyboard shows again.
> See screenshot here: http://imgur.com/NtQ4QSl
> In the above screenshot I clicked on the "submit registration" button before
> filling out the form correctly and triggering a validation error "confirm
> password". This caused the keyboard to hide and resulted in the page gap
> error as shown.
> The error also occurs when the keyboard is dismissed without hitting the
> "submit registration" button i.e. by using the dismiss keyboard button within
> the android nav bar.
