Comment (by johnjamesjacoby):

 In the above attachment (1x-artifacting.png) you'll see what happens when
 HiDPI mode is off, but 2x icons are rendered by the browser. To purposely
 duplicate this odd behavior:

 * Have a Retina MacBook Pro.
 * Connect Cinema Display.
 * Open Safari.
 * Move Safari 50% between the rMBP display, and the Cinema Display.

 The bbPress icons with thicker line widths render normally, the !WordPress
 core icons with thinner line widths render with artifacts as a result of
 the downsizing. Currently, apps and websites need to earn the right to
 render 2x content. 1x is the default display mode. If anything fails
 during this communication, and we push out 2x icons on a 1x display,
 slightly thicker lined, dedicated 2x icons render much more smoothly than
 the current icon32 implementation.

 It's edge-case, and you can argue it's the browser or OS's problem to deal
 with, but ultimately it impacts millions of users, and it's within our
 power to control.
