    Credit to peppe for informing us of the environment variable, but qputenv()only takes a QByteArray as the value parameter, so 1 won't work.

    The two options that work:

    qputenv("QML_DISABLE_DISK_CACHE", "1"); // or
    qputenv("QML_DISABLE_DISK_CACHE", "true");
    

    This successful disables the cache and prevents the associated bugs from manifesting.

    Add QML_DISABLE_DISK_CACHE (set to 1) to your environment variables. You should be able to do it inside your application via qputenv -- put it somewhere in main before loading QML content.
