I would keep the issue open, disabling virtualization is only a workaround that is not always acceptable.

@marbel82 I think that is a slightly different issue. In this case the DataGrid is manually copying the values onto rows and misses some.

Is your CheckBoxes issue resolved if you put a CheckBox in a DataGridTemplateColumn?
