Fragment of a discussion from File talk:Kdenlive-Quickstart-Add-Transition.png From my understanding, when you upload a new image and the displayed size change a new image is generated and immediately displayed. When the new image has the same dimension has the old image or the image is displayed with a fixed width, when the cached image is used. In this case, we need to wait around two weeks to see the cache invalided and the new image displayed. Hope this help.
