    Description

      I have a strange freeze in QGuiApplication that I could reduce to a minimum example.

      • Add QWebView to your project
      • Add QGuiApplication to your project and make a minimum HelloWorld example

      When I start this application it freezes in the constructor of QGuiApplication. The stacktrace shows this line where the freeze occurs:
      OpenGLTester::testDesktopGL() Line 375

      if (!MakeCurrent(dc, context))
          goto cleanup;

      When I remove the importĀ 

      #include <QtWebView> 

      the freeze doesn't occur.

      Also with Qt Version 6.5.3 the freeze doesn't occur even with QWebView active

      I had the chance to try it on a different machine with another NVidia card. It happens there too. But both machines have the same driver version. So the two machines where I could test it are:

      • NVIDIA GTX 1050 with Driver 546.01
      • NVIDIA GTX 1650 with Driver 546.01

      I will attach the minimum example on this issue. When the freeze occurs the console will print out only

      Before QGuiApplication app(argc, argv)

      and freeze afterwards
