title: Bottom of button disappears on different computers with same environment
body: <p>I'm facing issue with Java Swing. On one computer button looks <a href="https://i.stack.imgur.com/QHGLw.png" rel="nofollow noreferrer">one way</a>, but on other computers it's <a href="https://i.stack.imgur.com/7glJv.png" rel="nofollow noreferrer">different</a>. Any idea why?</p>
