Ah, sorry... my original description was perhaps a bit too concise. The GLCanvas is indeed part of a JPanel, which again is added to the CardLayout. The screen area underneath the GLCanvas is the part that is not properly refreshed.

The use of sun.awt.noerasebackground=true/false also doesn't make a difference.
