    Description

      Desktop application build with QT5.13.2 msvc2017 and Visual Studio 2019 16.4.1 on Windows 10 platform, deployed on Windows 10 pro 64 bits and Windows 7 32 bits.

      Running OK on W10 pro 64 bits but failure when running on W7, issue with QStackedWidget:: inserwidget.

      creating with QT designer 2 ui modules :

      Qmainwindow / Qwidget  / Qlabel / QStackedwidget including several other widgets plus a reference on

      Qwidget  / Qlabel / QStackedwidget / C_BottomPanel and C_TopPanel

       

      on W7, if this last widget is inserted, it fails to display the current widget of the qmainwindow, a transparent view is displayed.

      this does not happen on W10.

      As the build happens with msvc2017, i am afraid of directx12 api are linked  and could be the issue to run on W7 with directx 11 max.
