    Hi,

    You should add which version of Qt you are using.
    From time to time, it can also come from the graphics driver. What kind of hardware do you have ?

          @SGaist I am now on 6.7 but the issue still persits. 658c9c47-6712-4db9-a9d4-647d2aeb2975-image.png

          I tried both now commented out methods, none did really fix it.

          Have a nice weekend.

           #include <QGuiApplication>
          #include <QQmlApplicationEngine>
          #include <QSurfaceFormat>
          #include <QQuickWindow>
           
          int main(int argc, char *argv[])
          {
              //Both do nothing for me oc i removed the comments when testing :)
              //QCoreApplication::setAttribute(Qt::AA_UseOpenGLES);
              //QCoreApplication::setAttribute(Qt::AA_UseSoftwareOpenGL);
           
              //This makes it better, but still not gone
              //qputenv("QSG_INFO", "1" );
              //qputenv("QSG_RHI_BACKEND", "opengl");
           
              QGuiApplication app(argc, argv);
           
           
              
              QQmlApplicationEngine engine;
              const QUrl url(QStringLiteral("qrc:/QMLCourseLesson1/Main.qml"));
              QObject::connect(
                  &engine,
                  &QQmlApplicationEngine::objectCreationFailed,
                  &app,
                  []() { QCoreApplication::exit(-1); },
                  Qt::QueuedConnection);
              engine.load(url);
              
              
           
           
              return app.exec();
          }

              @SGaist The qml file is the standard one created when opening a new project out of the box. I also opened a view qml examples all have the same issue.

              import QtQuick
              import QtQuick.Window
              
              Window {
                  width: 640
                  height: 480
                  visible: true
                  title: qsTr("Hello World")
                  color: "white"
                  id: root
              
              
              
                  Image {
                      id: myImage
                      source: "https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRILAm29uLbvMPEEGffMvYiAdZvPFkYa-49nA&s"
                      anchors.centerIn: parent
                      width: 150
                      height: 100
              
                      Rectangle{
                          color: "red"
                          width: parent.width
                          height: parent.height
                          opacity: 0.5
                      }
                  }
              }

                    Have you checked, if the GUI is updated at all, with a button or timer that changes some colours?

                    I have the case, default apps don't update on dvi connected displays until I do some specific loops. It's supposed to be a grafiks driver issue of my adapter/docking station


                    Be aware of the Qt Code of Conduct, when posting : https://forum.qt.io/topic/113070/qt-code-of-conduct


                    Q: What's that?
                    A: It's blue light.
                    Q: What does it do?
                    A: It turns blue.

                      @J-Hilk Yep checked it, it's updated but the resizing issue does still occure. It also only occures with various apps made with qml. Programms coded with qt or any other framework do work just fine... thats really a pitty.

                      How do you exactly fix this problem?

                        Would i be viable to use qt widgets and just use qtquick for all the other widgets embedded into the qt widgets mainwindow or is this a bad idea?
