    I wonder if this is a case of needing "the common hack" of passing all of the Qt framework qml as the qmldir.

    My build script (yes, I run bash on windows) does it like so:

    windeployqt "${FLAVOR}" --qmldir "${WINALLQML}"  app.exe
    

    Where WINALLQML is something like C:/my_third_party_sources/Qt_desktop/5.15.0/msvc2019_64/qml

      You'll really want to see what the STDOUT/STDERR (console output) is printing when you launch the exe.

      There should definitely be a warning or an error printed that would clarify what exactly is going wrong.

      I don't often work on windows, so my knowledge of how exactly to see all the output is "spotty", but if you aren't seeing any output then I think you need to add CONFIG+=CONSOLE, as in...

      qmake.exe CONFIG+=CONSOLE path/to/project

        @KH-219Design
        Thank you for your reply.

        I have added

        --qmldir "${WINALLQML}" 
        

        to the windeployqt call, so the whole call looks like this :

         C:/Qt/5.12.2/msvc2017_64/bin/windeployqt.exe QtCreatorScrollProject.exe --release --qmldir c:\\Users\\<myUserName>\\Documents\\QtCreatorScrollProject --qmldir c:\\Qt\\5.12.2\\msvc2017_64\\qml
        

        but I still got the same result (empty window - QML contents doesn't appear).

          Why do you have 2 time --qmldir in your command line?

            Originally I only had one --qmldir . I added the additional one as per @KH-219Design 's suggestion.

                      @just_a_developer Sorry tweaking the arguments didn't help.

                      What about watching what Qt is printing when you launch the exe?

                      I would still expect there is a warning or an error printed that would clarify what exactly is going wrong.

                        A bit more info :
                        Here is the output of the app when I run it with QML_IMPORT_TRACE=1 :

                          @just_a_developer said in Qml contents doesn't appear under Windows:

                          "Accessibility Insights for Windows"

                          Wow! Bravo to "Accessibility Insights for Windows" . That's an amazing trick.

                          I noticed that earlier you mentioned that the machine where the problem occurs is a VM. I wonder if there is just an OpenGL problem/glitch due to the virtualization. Are there VM options/settings you can play with, like assigning your GPU, or toggling through various graphics acceleration options?

                            I am not sure if there is anything that I could do... It is a machine in vSphere and I don't really see any options that I could change which could be relevant...

                            But : here is a bit more info :

                            • the app works well under a Windows7 VM (everything appears, including QML contents)
                            • the app doesn't show the QML contents under Windows8 and Windows10 VMs (empty window - QML contents doesn't appear)

                            Here is the context of the Windows7 VM (as shown by OpenGL Extension Viewer), where the QML contents does appear :

                              OK : I got the fix : it is a rendering issue.

                              When I force rendering via ANGLE, it works : Options for forcing rendering via ANGLE :
                              1.: setting the QT_OPENGL environment variable to angle . (I only tested this solution, and it works well.)
                              2.: compile Qt with configure ... -angle .
                              3.: call QCoreApplication::setAttribute(Qt::AA_UseOpenGLES); before creating the QApplication object .

                              There is still an interesting thing : based on Qt's documentation, Qt libraries are compiled with -opengl dynamic which means that Qt should fallback to using the ANGLE renderer by itself (without me having to forcefully ask it to do that).
