Steps to reproduce

URL:

Repro Steps:

Open the test.html in IE11 on Windows 8.1 (all latest updated).

Notice how the image is blurred.

Inspect the element (<i>) and remove the three border radius styles on it.

Notice how the image is sharp now.

The issue seems to be combination of various rules like

  • line height
  • parent element’s margin (0px is ok; auto is not)
  • *, *::before, *::after {
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
    }
  • and may be more.

Expected Results:

No blur as in chrome/ff.

Actual Results:

Dev Channel specific:

No
