If you remove this, it is draw right, when the window is shown the first time. But as soon as the parent is redraw (for example when it is moved beyond the screen borders and back) the trackbar gets invisible. Any suggestions what to do against this?

Is there a way to retrieve the correct color, when the surface is filled with a single color?
