@dhdurgee: Oh, launchpad. Yep, that'll never do the trick
. The KUAL button will, though (in the snapshots, that is).
As for the root cause of the issue, if switching between books (and waiting the appropriate amount of time) doesn't help, then it's still probably a bug. Do you happen to have a weird USB setup? Or can pinpoint a significant (or not) detail before the desync happens?
If you can, when that happens, try to check the logs and/or check that the cover watchdog is alive (remember, house of cards, I might have missed a corner case).
Also keep in mind that there's a known race condition (in this branch of the code) where rarely, the first sleep cycle on a new cover will either use the previous cover, or a mangled mix of the two. There's a KUAL button to enable a workaround, which isn't the default because it has worse cosmetic downsides (IMHO)
. That race condition *might* have been fixed in the latest snapshots, but I wouldn't hold my breath.
