386544 - two squares, supposed to be identical, have different edges

Status: RESOLVED INVALID

(Core :: Graphics, defect)

Attachment: pic of squares at very high resolution, showing fuzziness on left square

I am running on a 2.16 GHz Intel Core Duo with 10.4.9 and 2 GB memory.

This difference is a bit subtle, but it is obviously there. See the attachment, which is a snap of a Pixie window that shows the problem at a high resolution.

Load the page from the URL above. There are two squares.

On 2.0.0.4, these look very different. The left one has an empty center. On a trunk build, the squares look the same.

The squares do have a difference, though. The edges of the right-side square are very sharp and clear. The left-side box has a rim, 1 pixel wide, on the top, left and right side. Is there a reason the edges of these squares should be different?

On the left, the square is painted as a character (text anti-aliassing/shading), on the right the test is using the border-property.
I see the same fuzziness in all browsers (WebKit, Opera, iCab, Minefield,...) fwiw.

The testcase requires the Ahem font.

Comment 3

Yes, I know that (and I have that one installed). But that doesn't change anything. Even with the Ahem font, the OS level font-smoothing technology comes into action.

What philippe said.  The glyph is getting FuzzyTyped(tm).
