I have a Retina display, and the favicon is faceless, plain, and depressing everywhere I go. Can we please fix this?

Easy Repro Steps:

  1. Open Chrome (haven't tested it on anything else)
  2. Zoom in (command-+ on a Mac) to 200%
  3. Go to Arduino.SE
  4. Observe the facelessness of the icon.
  • 'Tis fine on my end. (Vista, FF 26)

    It only does this on a Retina display.

Found the bug... when you zoom to 200% the code detects this and change the fav icons sprites file from this (16x16 icons) to that (32x32). (Very smart, team! :))

Now the only problem is, that while in the 16x16 sprite there is icon for Arduino, in the 32x32 it's just blank as you see yourself.

With proper icon:

And without:


Fixed by Jin, in revision 2014.2.??.1369.

    This was my fault. I've pushed the correct icons. The changes will be on live after our next prod build. (You may still have to hard refresh browser)

I'm getting the same issue in chat without a retina display.

no icon

The root of the problem appears to be different than what Shadow points out since it's pulling from a different location:

<img class="small-site-logo" title="Arduino" alt="Arduino" width="16" height="16" src="http://cdn.sstatic.net/arduino/img/favicon.ico?v=abcdef">



This may just be an error on your end. I would try to restart your computer and see if this fixes the problem. It may also be a zoom error. Try zooming in or out and see if it fixes the problem.

  • Nope, just reproed on a different machine. Try the steps above.
