    Default [BUG] Grid Panel with BufferedRenderer

    Hello, Nowadays I found out some bugs from grid with bufferedrenderer.

    When I resize a grid panel and scroll repeatedly,
    grid panel's scroller is going to top.
    Second, white spaces appear.

    I really wanna solve this problem. Is there anybody has a own solution?

    This youtube link is for how to reproduce bug.

    There is my bug example in Fiddle.

    I actually am seeing this as well but without even resizing. I'm using IE 11 and Ext JS 6.5.2. With ~300k records just dragging the scroll bar towards the bottom leaves me in a state with a bunch of white space and scrolling up and down sometimes works and sometimes doesn't. I am also using a buffered store and buffered renderer.

    I get this as well without resizing and ExtJS 6.6 and many records in a grid panel with buffered renderer. Manly on IE11 (we sadly have to support IE for our customers), but also occasionally on Chrome (Version 70.0.3538.110 (Official Build) (64-bit)). Really annoying. Any news on this?
