On Windows, running your Java application with -Dsun.java2d.ddoffscreen=false -Dsun.java2d.gdiblit=false may help removing the flickering effect.

I don't think it's a lightweight/heavyweight problem as one panel is not hidding an other. It could be related to http://www.vtk.org/Bug/view.php?id=7107

Which layout do you use in your main JPanel ?
