I think it is a bug in iOS 12.1. I have some large PDF files with multiple images. These used to display fine in iOS12 Books app. After the 12.1 update, most of the images do not display correctly in Books (smaller pdfs appear to be okay so far). They also do not display correctly in PDFExpert. However, these display fine when I use Adobe Acrobat app.

  • We still currently have the same issue as Jason explained it hereby. Notice that the issue is reproducible with some large PDF files with multiple images which are displayed from a WKWebView (WebKit) OR a PDFView (PDFKit)... I am currently looking for a workaround. I will keep you updated.

enter image description hereI think you can solve this problem by setting "preserve vector data" flag to false like below (do NOT put a check mark like the image below).
