[TIMOB-16358] Android: Webview flickers when scrolling for the first time

Webview with transparent or gradient background flickers when scrolling down for the first time in Android with SDK 3.2.0 GA. Once you scroll to the bottom and then scroll up again not produces this behavior. If webview backgroundColor is set with a color as 'white' or '#FFFFFF' works fine. Detected using SDK 3.2.0 GA and 3.2.X versions on Android devices (Samsung Galaxy S III Mini, Samsung Galaxy Tab 3, bq Aquaris 5). With SDK 3.1.3 GA doesn't occur this behavior. Test case:

 
var window = Titanium.UI.createWindow({
	title: 'Test',
	fullscreen: true,
	exitOnClose: true,
	backgroundColor: 'white'
});

var view = Ti.UI.createView();

var webview = Titanium.UI.createWebView({
	backgroundColor: 'transparent',
	url: '/test.html'
});

view.add(webview);
window.add(view);

window.open();
