When switching windows with Cover or Flip switch, if there is a minimized window, and it is selected, then the window unminimizes twice. One unminimizing animation occurs to the window in flip or cover switch effect, and another one is from the task manager to the desktop. These two animations go in parallel and finish in one window. This doesn't look very nice as with high animation speed it looks like flicker, and with low speeds you can actually notice the two animations and this doesn't make a lot of sense.
The desired behavior is to have only one animation or (what would be even better) no unminimizing animation at all, the window just zooming in from cover or flip switch.
