Extra white area when software keyboard opens

Hi, I have an ion-content page with an input control. I click on the input, and the software keyboard shows up.
However, there’s an extra white area on top of the keyboard. See follow pictures.

Does anyone have similar issues?


Find the root cause myself.
I have invisible img in the body, which will cause the scroll behavior wierd. The code is as follow.
No idea why it happens, but it works as expected after I remove the img.

<body ng-app="IonicApp">
    <img id="weixinShareLogo" src="~/Html/Share/logo.jpg" width="400" height="400" style="visibility: hidden; position: absolute; top: 0; left: 0" />
