When you click a tab on a JTabbedPane, components are not displayed immediately

I have an application that includes a JTabbedPane and two tabs with some components. My problem is that when I click on another tab, the components do not appear immediately; but when the mouse cursor moves over each component ( JCheckBox , JButton , etc.) of the tab, the components will appear, but not correctly (see the image below).

Thank you for your reply message, the problem was calling the repaint () component called when its position changed, the marker location should be changed every time the map is moved by a user or a page event, so I think calling repaint () caused a loop and another component draw correctly.
