Rounded Material Icons border and color problem

Question

I have included Material Icons Rounded to my webpage like this:

<link href="https://fonts.googleapis.com/icon?family=Material+Icons|Material+Icons+Round" rel="stylesheet">

And I have css code for rounded class

.material-icons.material-icons--rounded {
  font-family: 'Material Icons Round';
}

In the page, star icon looks like this:

If i increase the font-size it turns into this:

Where does that border coming from and how to remove it ?

Edit: I have created a pen to reproduce the problem https://codepen.io/anon/pen/wOJdMZ

@import "https://fonts.googleapis.com/icon?family=Material+Icons|Material+Icons+Round";
.material-icons--rounded {
  font-family: "Material Icons Round";
}
i {
   color: red;
}

.material-icons {
  font-size: 60px;
}

.size--2 {
  font-size: 90px;
}

<table>
  <tr>
    <th>Rounded</th>
    <td><i class="material-icons material-icons--rounded">star</i></td>
    <td><i class="material-icons material-icons--rounded size--2">star</i></td>
    <td><i class="material-icons material-icons--rounded">star_half</i></td>
    <td><i class="material-icons material-icons--rounded size--2">star_half</i></td>
    <td><i class="material-icons material-icons--rounded">star_border</i></td>
    <td><i class="material-icons material-icons--rounded size--2">star_border</i></td>
  </tr>
  <tr>
    <th>Not Rounded<br>
      <td><i class="material-icons">star</i></td>
      <td><i class="material-icons size--2">star</i></td>
      <td><i class="material-icons">star_half</i></td>
      <td><i class="material-icons size--2">star_half</i></td>
      <td><i class="material-icons">star_border</i></td>
      <td><i class="material-icons size--2">star_border</i></td>
  </tr>
</table>

UPDATE: Rounded icon colors are not changing on some screen sizes.

I have updated the code snippet which is attached to the question.

• On the 1920x1080 monitor, all icons are red.
• On the 2560 x 1600 macbook retina screen, rounded icons are black and the others are red. (This doesn't seem to be a problem on Chrome or Firefox)

UPDATE 2

The color problem is not solved. On the retina screens icons are not getting any color. They are always black. Need help about that.

Answer 1

There seems to be a problem with the glyph itself

If you download the SVG glyphs from here
https://material.io/tools/icons/?icon=star&style=round
and here https://material.io/tools/icons/?icon=star&style=round

you can see the rounded glyph is wrong and the pointy star is correct

You should file an issue to https://github.com/material-components

some info to the material team
