CSS3变换导致文本在Safari和Firefox Mac Yosemite中闪烁 [英] CSS3 Transform causing text to flicker in Safari and Firefox Mac Yosemite

问题描述

我在Safari和Firefox（Mac / Yosemite）上遇到这个奇怪的问题，导致当鼠标悬停在转换元素上时，页面上的几乎所有文本都会闪烁。

I'm having this weird issue on Safari and Firefox (Mac/Yosemite) that causes almost all of the text on the page to flicker when hovering over the transforming element.

示例gif：（Firefox，Yosemite）

Example gif: (Firefox, Yosemite)

.usp {
   //USP has an icon that is defined below
    opacity: .4;
    @include transition(all .3s ease-in-out);


    &:hover { 
        opacity: 1;
        @include transition(all .3s ease-in-out);


        .icon {
            @include transform(scale(1.1));
            @include transition(all 1.7s ease-in-out);
        }
    } // :hover
} 

.usp .icon {
    display: block;
    height: 75px;
    width: 75px;
    // Insert background-image sprite (removed from this example)
    @include transition(all .3s ease-in-out); 
    @include transform(scale(1.0));
}

我尝试过以下操作：

将这些样式的每个可能组合添加到正文，变换元素和/或其父

Add every possible combination of these styles to the body, the transforming element and/or his parent

-webkit-transform-style:preserve-3d;
-webkit-backface-visibility: hidden;
-moz-backface-visibility: hidden;
-ms-backface-visibility: hidden;
 backface-visibility: hidden;
-webkit-filter: opacity(.9999);
-webkit-font-smoothing: antialiased;
-webkit-transform: translate3d(0, 0, 0);
-moz-transform: translate3d(0, 0, 0);
-webkit-transform: translate3d(0, 0, 0);
 transform: translate3d(0, 0, 0);
-webkit-font-smoothing: subpixel-antialiased;
-webkit-text-stroke: 0.35px;

如果（样式如下）应用于正文，问题在Safari中修复，因为它不是webkit浏览器。

If (styles below) are applied to the body, the problem is fixed in Safari but not in Firefox as it is not a webkit browser.

-webkit-transform: translate3d(0, 0, 0);
-webkit-text-stroke: 0.35px;

我真的不知道是什么原因导致这个问题，我怎么解决它！

I have literally no idea what causes this and how I can fix it!

推荐答案

好的！

经过一个星期的测试，删除和添加CSS规则解决了我的问题。我原来在Firefox 39和Safari 9中都有这个问题，但是Firefox用最新的更新程序神秘地修复了自己。 Safari然而，没有。问题与页面上元素的3D渲染有关。我试图缩放的元素必须转换为3D上下文，页面上的闪烁元素在2D和3D之间切换，如@ Woodrow-Barlow在其他答案中解释。

After a week of testing, removing and adding CSS rules I finally found the solution that fixed my problem. I originally had this problem in both Firefox 39 and Safari 9 but Firefox mysteriously fixed itself with the latest update. Safari however, did not. The problem has to do with the 3D rendering of elements on the page. The element I tried to scale had to be transformed into 3D context, the flickering elements on the page switched between 2D and 3D as explained by @Woodrow-Barlow in the other answers.

添加

-webkit-transform: translate3d(0, 0, 0);

，因此在页面加载时将它们呈现为3D，他们不再需要切换！

to the flickering elements, and thus rendering them in 3D on page load, they no longer had to switch!
