Question

我有一个带有position:sticky的简单导航栏，滚动时滚动条显示不清晰，一切似乎都正常，那么它位于顶部。

从上图可以看出，似乎存在一些渲染问题。这是CSS：

body{
/*For demo purpose*/
height:300vh;
}
* {
    font-family: RobotoThin;
    margin: 0;
    padding: 0;
    overflow-x: hidden;
    outline: none;
    -webkit-transition: 1s;
    transition: 1s;
    box-sizing: border-box;
    background-repeat: no-repeat;
    transition: 0.5s !important;
   scroll-behavior: smooth;
}
div.window {

    display: -webkit-box;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
    -webkit-box-align: center;
    -ms-flex-align: center;
    -webkit-align-items: center;
    align-items: center;
    -webkit-box-pack: center;
    -ms-flex-pack: center;
    -webkit-justify-content: center;
    justify-content: center;
    box-sizing: border-box;
    padding: calc(2vh + 2vw);
    height: 100vh;
    width: 95vw;
    position: absolute;
    right: 0;
    top: 0;
    display: none;
    white-space: nowrap;
    display: flex;
    -ms-flex-wrap: wrap;
    -webkit-flex-wrap: wrap;
    flex-wrap: wrap;
    background-color: #ecf0f1;
    margin-left: 5vw;
}
#help{
    display:block;
    transition:0s !important;
}
div#help{
height:200vh;
    white-space: normal;
}
div#help  a{
    color:red;
    text-decoration: none;
}
div#nav {
  top: 0;
  position: sticky;
  display: flex;
  justify-content: space-between;
  color: black;
  background-color: white;
  padding-top: 1vmax;
  padding-bottom: 1vmax;
  font-size: 1.2vmax;
  flex-wrap: wrap;
  border-radius: 10em;
  box-shadow: 0 1px 3px rgba(0, 0, 0, 0.12), 0 1px 2px rgba(0, 0, 0, 0.24);
}

div#nav>a {
  color: black;
}

div#nav>*:hover {
  color: gold;
  letter-spacing: 0.3vw;
}

div#nav> :first-child {
  margin-left: 1vw;
}

div#nav> :last-child {
  margin-right: 1vw;
}

<body>
<div class='windows' id='help'>
<div id='nav'> <a>General important info</a> <a>Desktop</a> <a>Math calculators</a> <a>Notes</a> <a>Battery</a> <a>Quotes</a> <a>Settings</a> <a>Passwords and Data</a> </div>
</div>
</body>

不要介意颜色。我使用一个插件，因此您将看到所有白色，而不是黑色。奇怪的是，我无法使示例正常工作，因此我无法代表问题。希望您可以看一下我的代码，并找出可能导致此问题的原因。

反复摆弄之后，罪魁祸首是：

  overflow-x: hidden;

body {
  /*For demo purpose*/
  height: 300vh;
}

* {
  font-family: RobotoThin;
  margin: 0;
  padding: 0;
  /* overflow-x: hidden;     <-- The problem */
  outline: none;
  -webkit-transition: 1s;
  transition: 1s;
  box-sizing: border-box;
  background-repeat: no-repeat;
  transition: 0.5s !important;
