JTextField with transparent background not behaving well

Question

I am developing a chat app., where the user types all his info here, but the JTextField is not behaving really well, as shown in the image attached.

Answer 1

Wildly guessing: the field's opacity isn't set correctly to false, which produces the artefacts. The snippet below works just fine:

JTextField name = new JTextField(20);
name.setOpaque(false);
JTextField pass = new JTextField(20);
pass.setOpaque(false);
pass.setForeground(Color.WHITE);
// being lazy: use SwingX 
JXPanel panel = new JXPanel();
BufferedImage back = XTestUtils.loadDefaultImage("moon.jpg");
panel.setBackgroundPainter(new ImagePainter(back));
panel.add(name);
panel.add(pass);
