    Description

      Similar to QTBUG-58329. the patch I wrote for fixing that issue in 5.8 finally has conflicts and I can't fix them. So I'm reporting again to see the remaining issues fixed.

      Steps to reproduce:

      1. Connect two screens to a computer, preferably a bigger one on the right
      2. Set both to HighDPI (QT_SCREEN_SCALE_FACTORS=2;2)
      3. Open a Qt application on the secondary (right) screen (tested with Qt Creator)
      4. Right-click to open a context menu

      Expected results:
      The context menu shows under the mouse, as it does on the left screen

      Actual results:
      Context menu appears to the left. If the mouse click was within the left screen's size (in physical pixels) inside the right screen, the menu is shown at the edge of the left screen. If the click was further to the right than the left screen's size, the menu is shown in the right screen, but offset from the actual click position by the left screen's size.
