Since iOS 13 (including all recent betas) if a PDF page should have a background colour that colour isn’t showing and instead the page is white. I’m displaying the page with the PDFKit framework. I’ve also noticed that this is occurring in Apples own apps too like iBooks so no point posting code as it’s not my code specific. I’ve also noticed this only seems to happen for some users so appears to be either device specific or some other attribute. Has anyone here found this and indeed a solution ?
