Hi Alex, 

Greetings from Syncfusion. 

We were able to reproduce the issue “Contents in the PDF pages are distorted” in SfPdfViewer in Xamarin.Forms.Android and we suspect this to be a defect. We will validate the issue and update further details on 21^st Mar 2019.

Hi Alex, 

We are using native PdfRenderer of android to render the pages of the PDF document. On analysing the issue, we could see that the rendering issue is caused due to the native PdfRenderer of android only with High density devices. We could not see this image distortion with low density device. However, we have also provided options in PDF viewer Xamarin.Forms Android and Xamarin.Android to use Pdfium that is a third party open source PDF rendering engine. Pdfium is the solution for overcoming defects in native Android rendering. We could see that the pages are rendered properly with the PDFium rendering engine. We have also published  KB for using PDFium rendering engine in our PDF viewer control. Please refer the below link for more details.

The other render is not perfect but better. It's good enough for me. Thank you.
