How to turn off rounded corners in preview when viewing a PDF

I just upgraded to Tahoe and am not happy about how Preview by default rounds the corners of PDFs when viewing them. This is unacceptable. How do I turn this off?

PDFs are supposed to look consistent no matter how they're viewed and rounding the corners on a document is totally unneccesary and compromises the design of a PDF.

Overall, I'm not a huge fan of the UI updates in Tahoe and iOS 26. Liquid Glass is highly distracting. The rounded corners everywhere waste space. But while I can tolerate some of the new UI elements, changing how a PDF is viewed is where I draw the line.

Please for the love of God get rid of rounded corners in preview PDFs in the next Tahoe update.

Thanks!!!

This seems reassuring.

I do not see any round corners... How is that?

You're welcome. The round corners are only the frame of the Preview app. They do not change a PDF or image file. If the round corners overlap the file you can simply resize the Preview window or change the Zoom level of the file.
