QQuickView resize Lag

[l0calh05t]

When I use a QQuickView in a regular Qt application, resizes of the QQuickView contents display a significant lag. At first I thought it might be to rendering speed issues on my ultrabook, but after wrapping my QML object in a QML ApplicationWindow and running it as a pure QML/C++ application, resizing runs perfectly smoothly. However as QtQuick controls still have massive issues (Styling, incorrect Keyboard behavior on Menus, no resize grip in StatusBar etc.), so that is not a solution.

Is there any workaround to getting a faster resize? I am using Qt 5.3 / ANGLE / MSVC 2013
