Displaying a blank area of error, the list slides too slowly

[tcqq]

• [x] I have searched existing issues and confirmed this is not a duplicate

Issues and steps to reproduce

Issues one: Very slow when sliding the list. Issues two: Search input for "22", an error blank position will appear.

If I use flexbox's LayoutManager, the above problem will occur. If I use another LayoutManager (FlexibleFlowLayoutManager.java) with similar effects, the above problem does not occur.

The example contains two LayoutManagers for testing, the first one has the above problem, the second one does not have the above problem

Expected behavior

1. Sliding list should be smooth
2. Error blank location should not appear when searching

Version of the flexbox library

1.1.0-beta1
