      Description

      I have 2 displays:

      1) laptop/primary 1920x1080 (left)

      2) hdmi/secondary 2560x1080 (right)

       

      And I have widgets based Qt-only application with a toolbar. Some actions added to the toolbar have menu.

      If I open this menu (by clicking the toolbar button) on the primary display it's shown properly. If I move the application window to the secondary display and click the toolbutton there, the menu is shown on the primiary display aligned to its right edge, while Y coordinate looks valid.

      This behavour doesn't depend on menu size. I have 3 affected to these problem menus implemented in different time / different ways but all of them are affected, one of them is very small (a couple of short items). One of the menus comes from a QToolButton being added right to the form instead of QToolBar.

      Even so any context menu for the same window or a menu I render manually menu->exec(QCursor::pos()); is shown in the correct position. Menus set to QPushButtons also work properly.

       

       Minimal reproducible example

      #include <QApplication>
      #include <QMenu>
      #include <QToolButton>
      
      int main(int argc, char **argv) {
        QApplication app(argc, argv);
        auto button = new QToolButton();
        button->setText("button");
        button->setPopupMode(QToolButton::InstantPopup);
        QMenu *menu = new QMenu(button);
        menu->addAction("item");
        button->setMenu(menu);
        button->show();
        return app.exec();
      }
