grid go blank after scrolling

I am useing ActiveWidgets 2.6.4
After i scrolled in my gird, the header gets blank.
This is my code:
var nInokation = 0;
    
    function Data4Cell(nRow, nCol)
    {
        return nInokation + ":" + nRow + "." + nCol;
    }


    var grid = new AW.UI.Grid;
    grid.setCellText(Data4Cell);
    grid.setHeaderText("header");

    grid.setColumnCount(20);
    grid.setRowCount(10000);

    document.write(grid);

    document.write("<br>");

    setInterval(function()
    {
        nInokation++;
        grid.refresh();
    }, 1000);

Thanks in advance

Thank you for the sample code - I can reproduce it in the latest Chrome. It looks like some sort of weird Chrome rendering bug.

I am looking for a workaround.

Found any suggestions?

Here is the code that should fix it:

.aw-chrome .aw-scroll-bars {
    visibility: inherit!important;
}
