Have any details? I have a retina screen and don't have any CPU usage issues.

  There are many bugreports known to Mozilla already. Here's mine: https://bugzilla.mozilla.org/show_bug.cgi?id=1407536 https://bugzilla.mozilla.org/show_bug.cgi?id=1407536

  AFAIK, it's a known issue with retina screens and scaled resolutions. If you use the default resolution, you should not see any issue.

    The default resolution has been a scaled resolution for years now.

      I think GP means non-integer scaling

        So do I. My MacBook Pro came out of the box supersampling at 3360x2100, or 1680x1050@2x. The screen is only 2880x1800.
