If you have an Apple ID, you can use it to sign on to 
and fill out a bug report.

If you don’t, the are easy to get.  Go to (e.g.) System Preferences -> iCloud on your mac.  There’s a link to create one.



PS: your problem sounds like an issue with PDFKit, used by Safari, Preview, Skim, and others.
