That's what I had initially included in the report, but it's not true. It only displays an extra message/window at the beginning of the opponent's upkeep.

You can see that it triggers on its controller's upkeep, if you control Power Struggle and at least one other permanent with an ability that triggers at the beginning of your upkeep. In that case, Power Struggle will be highlighted in orange/red when the game is asking you to choose the order in which triggers are triggered.
