Setting the Border Pixel

When creating a window with a visual that is not the default visual, applications must set the border_pixel value in the window attribute structure, or a BadMatch error occurs. This is a common programming error that may be difficult to debug. For information on setting the border pixel, see the XCreateWindow man page.

If you are experiencing improper graphics and double-buffering performance (such as lack of acceleration), OpenWindows might not have been installed as root.
