JFrame pixelated components

Question

I have created a Java GUI useing java.swing
When i run my program the UI is pixalated:

enter image description here

this is my Panel with all the componets:

public GuiPanel(){
    super();
    this.setBorder(new EmptyBorder(10, 10, 10, 10) );
    //Layout:
    GridBagLayout gridbag = new GridBagLayout();
    GridBagConstraints c = new GridBagConstraints();
    this.setLayout(gridbag);
    setUpJButton();

    //textField
    c.fill = GridBagConstraints.HORIZONTAL;
    setUpTextField();
    c.gridwidth = GridBagConstraints.REMAINDER;
    gridbag.setConstraints(textField, c);
    c.gridwidth = 1;//reset gridwidth
    this.add(textField);

    c.insets = new Insets(10, 0, 0, 0);//padding to top

    //anmelden Button
    c.fill = GridBagConstraints.RELATIVE;
    setUpJButton();
    c.gridwidth = 1;
    c.anchor = GridBagConstraints.LAST_LINE_START;
    this.add(logInButton, c);

    c.insets = new Insets(10, 5, 0, 0);//padding to left

    //abmelden Button
    c.fill = GridBagConstraints.RELATIVE;
    c.anchor = GridBagConstraints.LAST_LINE_END;
    c.gridwidth = 1;
    this.add(logOutButton, c);
}

i've been googeling for hours but i didn't found a solution for this problem.

There are similar problem reported and I think the problem was caused by a driver issue. Upgrade if you can your drivers. — Eypros, Nov 17 '14 at 10:15

This looks like an OpenGL problem. Drawing of user interface components is usually done hardware accelerated. Specifically with OpenGL and DirectX in Java. You can try to

update your driver
try to fall back to software rendering by passing -Dsun.java2d.opengl=false -Dsun.java2d.d3d=false as command line option to the JVM.

You can find a whole list of options to control the rendering in Java2D in this article: https://docs.oracle.com/javase/7/docs/technotes/guides/2d/flags.html
