Reader reloads and loses position when coming from background #309

Open triin-ko opened 1 year ago

triin-ko commented 1 year ago

Bug Report

What happened?

If the reader view of the test app has been in the background and other apps are using a lot of memory, then something crashes and the book is reloaded and opened at an incorrect page.

Expected behavior

Book should stay on the same page as it was before going to background.

How to reproduce?

  1. Open a book with a saved location
  2. Swipe to some other page
  3. Send the app to the background
  4. Open other apps (I played a few games. This reproduced the issue every time: Diablo Immortal -> Candy Crush Saga -> Candy Crush Soda)
  5. Open the test app
  6. Reader view goes blank for a moment and then jumps back to the initial page
