Issue

KOReader occasionally only shows a black screen when the reader is woken up from sleep. The same can happen if you switch between apps and switch back to KOReader.

KOReader only shows a normal view again when you close and reopen the app or restart the reader. Reopening KOReader does not always lead to success.

Steps to reproduce

The error is difficult to reproduce as it does not always occur. The error seems to occur less frequently if no other app is running in the background.
