QPixmap are implicitly shared. So this means that when you do a = b, a

of it is destroyed.
OK, so here's an idea. The problem lies more or less in
Loader::Impl::createPixmap(), here:
image_.reset(cached_item_->image()->clone());
bool const success = image_->setPixmap(params_);
The first line clones the original image, if I'm not mistaken, and all
the transformations then happen in the call to GuiImage::setPixmap().
But the cached original remains. So can we clear that once this has
happened?
