Suggestion:

        g.drawLine(stkWidth/2, h-(stkWidth-stkWidth/2),
                w-(stkWidth-stkWidth/2), h-(stkWidth-stkWidth/2)); // bottom line

If you change the initial `x` to be `stkWidth/2`, it always aligns with the rectangle drawn in `paintBorderRect`. Thus the issue where the bottom highlight line is short of a few pixels gets resolved.
