Rewrite RcxTooltip to use WA_TranslucentBackground with a single contiguous QPainterPath (rounded rect + arrow notch). Pre-set the DarkTitleBar property to prevent DarkApp from calling DwmSetWindowAttribute which breaks layered window compositing. Dismiss all popups (including arrow tooltip) on alt-tab via MainWindow::changeEvent(ActivationChange).
