Windows: Missing expose event when window size is reduced

    XMLWordPrintable

Details

    • 20a29fbfe834c108517a23db359827d067246ecd (qtbase/5.6, 23.2.2016, 5.6.1)

    Description

      The expose event is not delivered to QWindow on Windows when window size is reduced vertically or horizontally. This causes that QWindow::paintEvent(QPaintEvent *) or QOpenGLWindow::paintGL() is not emitted in this case.
