Hi everyone! I am working on a free draw project but I've been stuck. I am trying to create a XPanelGraphics (extended JPanel) in which I can draw. The user can either draw or erase what he/she has drawn. I use jLayeredPanel with two layers, xPanelGraphics both. Here is the code of the XPanelGraphics

The problem is that it is really slow. For example when I am trying to draw a circle quickly, the result I get is what you see in the attached png file. Is there a way to make it faster?
