Description

In Ultra View Mode, PDF documents are slowly rendered when using a Safari browser. Sometimes the next pages turn grey and cannot be rendered.

Steps to Replicate

Prerequisite: Create/get a PDF document that has more than one page, and an iOS device with Safari browser installed.

  1. Log into Blackboard Learn Ultra Experience as an administrator

  2. Create and access an Ultra course

  3. Go to Course Content > Ꚛ Add Content> Upload > Upload the PDF document

  4. View the uploaded PDF using a Safari browser

Observed Behavior:
It will take a long time to load the first page of the PDF document, the next pages will take a longer time to be rendered while scrolling down, and sometimes they don’t (a grey frame will appear).
​Expected Behavior:
The PDF document can be loaded fast, and all pages can be rendered.
