    Hello,

    I am trying to load a Chrome Trace Events json file in Qt Creator by following the steps mentioned here.

    But for some reason the Visualization Tab is being rendered completely blank.
    I can see entries in the statistics tab about various function calls, but I don't see and timeline being rendered at all.

    I am using the Qt Creator package available from Ubuntu 20.04 LTS.

    Here is the output from the console for the exact version string:

    $ qtcreator -version
    
    Qt Creator 4.11.0 based on Qt 5.12.8
    
    ........
    

    I even tried it on another system with Fedora 34.
    I can see the same behavior.

    I even tried capturing various application with Lttng also and using the ctf2ctf tool for conversion to the JSON format to no avail.

    Is there a prerequisite to create a project in Qt Creator to utilize the feature?

    Regards,
    Ameya Vikram Singh

      It took sometime to figure out the missing library.
      It seems the qt-creator package does not install some of the libraries.

      I had to install the following library package using the package manager to get the functionality working:

      qml-module-qtquick-controls2
      

      It would bet great if the qtcreator GUI itself reported about the missing libraries.
      Instead of dumping it on the console.
