表格中的ExtJS 5 Combobox

Question

I have a question. When I open the combo box, the list is always transparent, that I see the elements behind it. What can one do against?

The form will be open in a new window, wenn a Button was klicked.

The code of the Combobox:

{
  xtype: 'combo',
  fieldLabel: 'Material',
  store: material,
  queryMode: 'local',
  displayField: 'name',
  valueField: 'abbr',
  editable: false,
  labelWidth: 150,
  width: 300
}
