除非显示为<object>，否则SVG模糊

Question

下面是我的iPhone 5s Safari的截图：

​

​

前两个 SVG图标显示为<object>。

<object data="/svg/tabbar/tab_1_active.svg" type="image/svg+xml"></object>

第三 SVG图标显示为<img>

<img src="/svg/tabbar/tab_1_active.svg">

第四 SVG图标显示为inline css background。

background: url("data:image/svg+xml,utf8,<svg ...> ... </svg>") //use of base64 does not change anything

问题:正如您可以看到的那样，的问题是，除非SVG不是以<object>的形式显示，否则它是模糊的。我不知道是什么导致了模糊。由于缓存的原因，我想将我的SVGs用作<img>或css bg。你有什么想法吗，如何使它不模糊？

在IE11和Chrome中，没有模糊。
