Scrollview inside ScrollableView: displaying half pages again (3.1.2)

SDK 3.1.0, 3.1.1, 3.1.2

iOS

I have a ScrollableView and adding some Scrollviews with images into it.

var scroll_view_content = Ti.UI.createScrollableView({});
var sv = Ti.UI.createScrollView({ width : deviceWidth, height : deviceHeight, top : 0, bottom : 0, showVerticalScrollIndicator : true, showHorizontalScrollIndicator : true, zoomScale : 1, maxZoomScale : MAX_ZOOM, minZoomScale : 1, cacheSize : 5})
// create image
var img = Ti.UI.createImageView();
sv.add(img)
scroll_view_content.addView(sv);

SDK 3.1.0 works fine! I had to add some changes and wanted to compile it with 3.1.2 but now I have wrong images again (same with 3.1.1). If I start scrolling some images are display half and the other half is already the next image!

There was a bug fix with scrollviews inside scrollable view in 3.1.0 but I can't find it at the moment. Is anyone having the same issue?
