      Description

      When using `QIcon::fromTheme` to select icons from an icon theme, the cache is overly aggressive and returns the same pixmap after setting the new theme with `QIcon::setThemeName`.

      The attached patch resolves this by clearing the in-memory cache when `setThemeName` is called.
