jbutton RGBA glitch

Question

I am using RGBA for the coloring. I want the button transparent, but to be able to set the degree of transparency, hence the alpha. Now it looks fine until I do anything that calls a repaint/paint like hover or focus. If I set opaque to false, it does make it transparent, I just don't want this 100% transparent. It is not the image I paint in the background either. It does not have a problem with RGB, just RGBA.

these don't work:

jButton1.setContentAreaFilled(true or false);
jButton1.setOpaque(true or false);

Here is my jButton color code:

jButton1.setBackground(new Color(255,0,0,100));

Here is what it looks like. jbutton glitch

Your problem looks something like this. The answers there may help you get the translucency right, but you'll need to do it in a custom ButtonUI, illustrated here.
