I have a snippet that change the color of a JTextField : textField.setBackground(new Color(155, 0, 0, 155)); When the color is changing, the component has a strange behaviour: the cursor twinkling becomes not regular, as so the color opacity that seems to change on ongoing repaint events.

In the main-method we set some "parameter...
