Look at the clock "icon", it's squashed vertically.

If you apply 4:3 aspect ratio, it becomes round.

Note that "icon" here is the minimised state of the window, and the clock application draws itself in that state with the same code as in the normal state, and so it utilises screen metrics, while other minimised applications just call default windows procedure which puts bitmaps on the screen.
