I have a KT4.
Koreader is set to "leave screen as is" for screensaver.
I use a custom program (https://github.com/yparitcher/kindle-zmanim) to dynamically set the screensaver
It uses fbink dump/restore to save and restore the current screen
when using koreader's night mode if i wake the kindle quickly the screen is correct (night) however if i wait (allowing the device to suspend) when i wake the kindle it refreshes after 1-2 secs white (black ink on white background) koreader wins the race
if i remove my custom wakeup handling code it works correctly
is there a easy way to check if koreader is active and let koreader do the refresh? or maybe some way of hooking into koreader's screensaver callback?
