title: EGLFS QML Screen not rotated
body: <p>I have Debian Bullseye, Intel Celeron J1800 with integrated graphics. Qt from Debian version 5.12.5</p>
  
  <p>Trying to rotate screen to portrait mode.</p>
  
  <pre><code>QT_QPA_EGLFS_ROTATION=90 /opt/app/bin/app
  </code></pre>
  
  <p>But window just resized, scaled up about 120%.</p>
  
  <p>My code</p>
  
  <pre><code>#include &lt;QGuiApplication&gt;
  #include &lt;QQmlApplicationEngine&gt;
  
  int main(int argc, char *argv[])
  {
      qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard"));
      QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
      QGuiApplication app(argc, argv);
      QQmlApplicationEngine engine;
      engine.addImportPath("qrc:/");
      const QUrl url(QStringLiteral("qrc:/main.qml"));
      QObject::connect(&amp;engine, &amp;QQmlApplicationEngine::objectCreated,
                       &amp;app, [url](QObject *obj, const QUrl &amp;objUrl) {
          if (!obj &amp;&amp; url == objUrl)
              QCoreApplication::exit(-1);
      }, Qt::QueuedConnection);
      engine.load(url);
      return app.exec();
  }
  </code></pre>
  
  <p>And QML</p>
  
  <pre><code>ApplicationWindow {
      id: window
      visible: true
      flags: Qt.FramelessWindowHint
      StackView { ... }
  }
  </code></pre>
  
  <p>QWebEngineView and widgets works well</p>
