When document with large images (the original image cannot fit on the page without resizing) are exported to PDF, the PDF document is visualized distorted by Adobe Reader. The issue is regression, introduced in 2017 R1 SP1. Workarounds: - Use images that can fit on the page. - Zoom RadRichTextBox to scale which allows the large images to fit fully on the page. The fix is available in LIB Version 2017.2.627.
