Dear all,

Our application switches between a GLCanvas to offer a 3D view and a several Swing JPanels to offer a various 2D views. For convenient switching, we use a CardLayout.

We experience a problem with the painting of the Swing views when switching from GLCanvas to Swing. Directly after the GLCanvas is interchanged for a Swing JPanel, the Swing JPanel shows a flash of garbage (one frame) before drawing its proper content. Crudely put, it seems Swing realizes too late that a repaint is required.

If we replace heavyweight GLCanvas with lightweight GLJPanel, then this refresh problem doesn't occur.

Looking forward to any thoughts that might help to find a solution.
