I have a Kobo Glo running firmware 2.3.1, and I've been bit by the bug that displays the wrong book cover when I sleep my device.
In odd moments at work today, I've been experimenting with ways to force the right covers. Here's what I've been doing.
First, displaying full-screen covers during sleep almost always seemed to be wrong.
I turned off the full-screen option and got six or seven right covers in a row. These were all books I had been reading recently.
I tried displaying some covers of books I hadn't read yet on this device and right away hit a book that displayed the previous book's cover. However, it had opened to the table of contents, not the cover. I paged back to the cover and displayed it while reading the book, and then slept the Kobo. This time it displayed the right cover.
The very next unread book's cover wouldn't display during sleep even when I paged back to it. It kept displaying the cover of the previous book. However, I managed to force it to display correctly (I think) by turning off the cover display feature in Settings, sleeping the device, then turning cover display back on. Now it displays normally.
This version of the bug does seem more complicated than the previous version, which always displayed the previous book's cover. With that version of the bug, you could just sleep the Kobo twice to get the right cover.
So my recommendations for a current cover-display workaround are...
1. Turn off full-screen covers.
2. If a cover doesn't display, try paging to it while reading the book.
3. If that doesn't work, toggle cover display as described.
Most of all, experiment yourself. I look forward to what you find out.
Caveats: I am not a professional software tester, and as we know. Kobos can vary widely, even among the same model and firmware versions.
