Android tabs - messy switching

I’m seeing that the switching between tabs on Android isn’t clean as it is on iOS. When I select a tab, the old view disappears completely (so blank background is visible) and then the new view is shown. This takes about 200ms and doesn’t look very good. It’s almost as if a transition is being attempted.

On iOS the view switches cleanly when you change tabs.

I’m using ionic 1.1 and crosswalk on Android. This is seen on a Samsung S4.
