    Description

      When modifying the code to use window.showFullScreen(), the triangle and text are not drawn and warnings are printed:

      QOpenGLWindow::beginPaint: Failed to make context current
QPainter::begin(): QOpenGLPaintDevice's context needs to be current
QPainter::begin(): Returned false
QPainter::setWorldTransform: Painter not active
QPainter::setWorldTransform: Painter not active
QPainter::fillPath: Painter not active
QPainter::setWorldTransform: Painter not active
....

      This might a manifestation of some issue that needs to be documented?
