I have this igGrid configuration:

        $("#grid1").igGrid({
            rowVirtualization: true,
            columns: [
                { headerText: "Product ID", key: "ID", dataType: "number" },
                { headerText: "Product Number", key: "ProductNumber", dataType: "string" },
                { headerText: "Price", key: "Price", dataType: "number" },
            ],
            dataSource: CreateDataSource(),
            height:'420px',
            width: '600px',
            features : [
                {
                    name: 'RowSelectors',
                    enableCheckBoxes: true,
                    enableRowNumbering: false
                },
                {
                    name: 'Selection',
                    multipleSelection: true
                },
                {
                    name : "Resizing"
                }
            ]
        });

The problem is that the header disappears and the coloring of the checkboxes is wrong when scrolling the page.

This is the initial status:

And this is after I select three rows and move down using the scroll bar:

In addition, the grid does not allow me to use the checkboxes.

Is there any workaround or planed date for a fix?
