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).
