I am evolving here the specification : the images stored are stored with their HiDpi size (width * dpr, height * dpr), and then some metadata is written. When reading the cached version for large, the user expects a 256*256 (modulo aspect ratio) and can find a (256 * dpr, 256 * dpr) image (or can read the devicePixelRatio from metadata) You can see in https://phabricator.kde.org/D29526#C575294OL738 and line 582 how to detect and handle such a case. > How would cached thumbnails work cross-screen? Cache thumbnails with low dpr will look blurry on hidpi screen, other than that's not an issue. We would need applications to update to use Hidpi thumbnails to renew thumbnails. I might want to evict low dpr thumbnails.
