    Hey,

    As topic says my application crashes when using WebEngineView component in qml. It crashes on exiting app/destroying object. Checked example "quicknanobrowser" and it's the same.

    I think it's somehow connected to ANGEL module but I'm not sure. I'm using old PC with windows 7, there is no OpenGL 2.0 support.

    Qt Version: 5.6
    Compiller: msvc2013 32bit
    OS: Windows 7

    How can I prevent? Is there any workaround?
    Thanks in advance

      Hi,

      Do you mean you don't have any OpenGL support ?

        Just checked, got OpenGL 2.1 support. I thought it may be related since qml uses OpenGL but I might be looking in wrong place.

        Any idea what can cause crash?

          No idea yet, but did you run your application through a debugger ?

            That's the best part, running debug version will not cause a crash, only release version. And running release version through a debugger points to some deassembler part.

            What's strange it does not crash on every windows machine, only on some.

              Are you running it from Qt Creator ?

              Which version of 5.6 are you using ? The Beta ? RC ?

                  Since 5.6.0 is out, can you check again against it ?
