    Default IE11 - data disappears on scrolling up (Ext 6.5.3)


    In a grid, i have loaded around 300 records and tried to scroll down vertically.
    After scrolling for 100 record I tried to scroll upwards.
    Now while scrolling up I have observed all the column data going blank.

    This isssue is observed only in IE11 and working fine in other browsers

    I tried giving trailingBufferZone : 50, leadingBufferZone: 60, which didn't work.

    Please let me know if this can be fixed in any other way

    Hello Sri Vidya,

    If Grid has BufferStore then it may show blanks due to network glitch or low bandwidth because while the record is storing in view for a fraction of the second the field will appear blank.

    Could you provide fiddle to replicate this issue? I have tested in all browsers, I have seen the same behavior

    Reference fiddle :
