Description
The synchronous QWidget::repaint() has been documented as "not recommended" for long, and it does not work with modern window managers. We need to draw within the frame we have been assigned and mark the window as dirty if we want a repaint (which is what update() does).
In Qt 5.15 we should deprecate it so that it can be removed in Qt 6.
