Here is an example of a "sketcher" component as a sibling of a JoGL window:

JitterProblemJoGL.java

When you move the mouse quickly on the sketcher, the rendering slows way down (depending on your hardware, if its fast, you might need a lot of scribbles before it starts slowing down).  If you change the "show_problem" variable defined at the top of the class to false, then its fixed.  Is this expected behavior?  Why does the repainting of the GLCanvas fire a refresh of the sibling component?  Is there a workaround for this?

Another (much smaller) issue is shown when the "use_panel_above_canvas" variable is set to true, the canvas does not get shown.

Thanks!
