Are you saying the image does not load at all, or that this is the image that gets cut off when you change to a circle container? Curious why you can’t show a screenshot of it being cut off. The only advice I can provide is to make sure your image is a 1:1 ratio (square), and that you have enough of a border to account for any cutoff around the edges that may occur.
The fact that you can show a PDF in an image component is an unintentional feature that has always existed, but was never planned or officially supported by Glide. Generally whenever it does work, it’s only going to show the first page of multi-page PDF, so it’s not always beneficial. In your case, there may be something unique with the PDF itself that prevents it from rendering as an image. Hard to say without having a copy of the PDF.
I think most of us tend to use a web embed component to view and interact with PDFs. Even then, it is a little bit of setup, but makes for a nice way to view multi-page PDFs within the app.
