I have $scope.items = [item1, item2, etc...] and ng-repeat="item in items" in html.
When I change $scope.items = [anotherItem1, anotherItem2, etc...], there is a delay in rendering.
The result is that I see the first array, than I see the 2 arrays combined (for 300ms), then it renders and shows only the second array.

EDIT: The ng-class is delaying too the render...
