- If the file looks the same in the Preview app, the problem is file specific. We're sure that Apple is aware of such cases if any and a new macOS update might fix the problem - still, you may want to contact Apple Support to make sure your vote is added for the fix they have registered.
- If the file looks good in the Preview app but doesn't load at all in PDF Expert, please contact us at rdsupport@readdle.com and, if possible, share the affected file with us - we're happy to help you personally. If the file's size is too big for sending it over email, you can upload it to any cloud storage service and share a link with us - e.g., you can use the WeTransfer service.

Such a file can also look like a checkered background - in this case, it means that the graphics are heavy and our app needs some time to load the content.
