You have the border of the tabPanel and the border of the item panel

Ext.create('Ext.tab.Panel', {
    width: 400,
    height: 400,
    renderTo: document.body,
    plain: true,
    border: false,
    items: [{
        title: 'Foo',
        border: false
    }, {
        title: 'Bar',
        //border: false,
        tabConfig: {
            title: 'Custom Title',
            tooltip: 'A button tooltip'
        }
    }]
});
