#Form{
background-color: rgb(67, 87, 83);
}
QSlider::groove:horizontal {
border: 1px solid #4A708B;
height:15px;
/*必须有这两句，一句也不能少，不然高度是默认高度。
groove:槽
*/
}

QSlider::sub-page:horizontal {
background-color: rgb(0, 255, 0);
border: 3px solid rgb(255, 85, 0);
height: 15px;
border-radius: 7px;
/*按钮左边*/
}

QSlider::add-page:horizontal {
background: rgb(170, 170, 255);
border: 3px solid rgb(170, 255, 0);
height: 15px;
border-radius: 7px;
/*按钮右边*/
}

QSlider::handle:horizontal 
{
  background: qradialgradient(spread:pad, cx:0.5, cy:0.5, radius:0.5, fx:0.5, fy:0.5, 
    stop:0.6 #45ADED, stop:0.778409 rgba(255, 255, 255, 255));
    
    width: 15px;
    border-radius: 7px;
}/*按钮*/

QSlider::handle:horizontal:hover {
    background: qradialgradient(spread:pad, cx:0.5, cy:0.5, radius:0.5, fx:0.5, fy:0.5, stop:0.6 #2A8BDA, 
    stop:0.778409 rgba(255, 255, 255, 255));
    width: 15px;

}

问题：

 放到最左侧或最右侧时，会有破绽。

如何解决呢？
