Answer 1

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.

Answer 2

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.
