A popup's position is meant to be relative to its nearest parent item. If this item exists in another window, the position needs to be mapped between the windows. We use mapToGlobal(QPointF) to figure out where to position the popup window. However, if mapToGlobal(QPointF) is called before the parent window is exposed, it will on Windows and X11 assume that the parent windows position is (0,0). This means that the popup window's position will usually be wrong, when it's opened at the same time as the parent window. To work around this issue, we wait for the parent window to be exposed, before opening the popup window.
