However, if your window only contains static elements, Qt will cleverly avoid repainting it until something changes. But why does it make a difference? An animated item causes the window to be repainted every frame (typically 60 times per second). After some experimentation I observed that adding an animated item (such as a spinning BusyIndicator) solves the problem.
