Android : KitKat Animation and WebView rendering issue

I am facing a rendering issue when running animation to simple View. My setup has ViewPager and the first Fragment contains a WebView and the second Fragment has custom progress indicator which I animate.

Following image shows the problem, somehow there is relation with the WebView although the indicator is fully in it's own Fragment. My guess is that the platform uses the same GPU renderer and when having a WebView there it gets broken.

Anyone had same issue/found a workaround?

Thanks.
