This is related to the standard look and feel on Ubuntu it seems. The default look and feel also makes text boxes and dropdown boxes to look ugly.
If I comment out GuiFrame.java:526 UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
I will get an entire different look and feel but it fixes this issue and the same with the textboxes.
