I have a serious problem with an increasing CPU and RAM usage in an ionic app with createjs library. The problem cause the app to crash after a while. As I am navigating between pages where each page has a new canvas, I see the RAM and CPU to dramatically increase. There is no memory leak. I have tested it with chrome developer tools.

After so so much testing, the solution was to treat each template page in ionic as a root page. So when I was navigating to a new template page I always did:

          $ionicHistory.nextViewOptions({
            historyRoot: true,
            disableBack: true
          });

          $ionicHistory.clearCache();
          createjs.Tween.removeAllTweens();
          $scope.stage.removeAllEventListeners();
          $scope.stage.removeAllChildren();
          $state.go("lesson", {}, {reload: true});

This way all cache that ionic kept was cleared and every event, tween motion and element in createjs was cleared too. This increased the speed of the app drammatically!
