＆＃34; <a>&#34; tags change color when a transition occurs anywhere in the page. Is this a bug?

Question

I'm using bootstrap 4.0 beta and I created a footer with the grid system.

When a transition occurs with this specific css set up the anchor tags slightly change color and even thickness increases a bit, here the example:

With a simple transition like this for an image that has nothing to do with the links on the footer:

.gallery-item:hover img {
  transform: scale(1.2);
}

我在Chrome和Firefox中进行了测试，到目前为止只在Chrome中发生，如果这是一个但有解决方法吗？真的很烦人。

到目前为止，我已经尝试了以下内容：

• 删除所有脚本以放弃一些javascript干预
• 尝试更改/增加z-index以确保元素位于顶部

当每次旋转木马自动滑动时添加自举旋转木马时，页脚上的链接将再次变得模糊并稍微改变颜色。

感谢任何帮助。
