SVG fill artifact in Chrome

Question

I have one polygon path, which is filled with a color. This works perfectly in Firefox and IE.

In Chrome depending on size - artifacts appear. In the example here, there is a diagonal gradient, instead of a plain color.

Question, how can I solve this, or what workarounds exist?

If the bug is not visible, width has to be changed, as its not always triggered. In JSFiddle that is very simple, as the size of the preview container can be easily changed.

The bug only happens when shaperendering is not set to crispedges.

svg {  
    backface-visibility: hidden;
    width:50%;
}
.auto {
    fill: #37d0cd;
    shape-rendering: auto;
}
.crisp {
    fill:#37d0cd;
    shape-rendering: crispedges;
}

Answer 1

So I found a workaround - but it feels like a hack. Therefor I am not really happy with the solution; I hope there is a better way.

Basically the fill color gets shape-rendering crispedges - which creates a pixelated border. To get rid of the pixelated border, I add same path again gave it a transparent fill and shape-rendering auto.

svg {  
    backface-visibility: hidden;
    width:50%;
}
.auto {
    fill: #37d0cd;
    shape-rendering: auto;
}

.crisp .a {
   stroke: #37d0cd;
   fill: transparent;
   shape-rendering: auto;
}

.crisp .b {
   fill: #37d0cd;
   stroke:transparent;
   shape-rendering: crispedges;
}

    <path d="M120 0C78.3 0 69.2 7.5 52.4 27.3 35.7 47 0 50 0 50h438s-35.2-2.6-52.4-22.7C368.4 7.3 359.6 0 318 0z" />

    <path class="b" d="M120 0C78.3 0 69.2 7.5 52.4 27.3 35.7 47 0 50 0 50h438s-35.2-2.6-52.4-22.7C368.4 7.3 359.6 0 318 0z" />
    <path class="a" d="M120 0C78.3 0 69.2 7.5 52.4 27.3 35.7 47 0 50 0 50h438s-35.2-2.6-52.4-22.7C368.4 7.3 359.6 0 318 0z" />
