Keyboard open causing weird effect

My app has a form in the home. When I click the input, the webview moves down like 30% of the screen. After that it makes a fast move, sliding up the webview in a very fast animation.

The space above the webview is whole black while this.

Im using beta 14, ionic cli 1.2.13 and cordova 4.1.2.

Im still looking for a solution, but maybe someone has an idea already

UPDATE

Ok, after some tries I discovered that the “reason” is cause I have an element with fixed height above the form. Still unsure about WHAT is the problem, but it’s something.

UPDATE

I changed to scroll=“false” and it worked.
