I just got a Nook HD for testing and noticed what I think is a bug.
My config is set to 640x960 with letterbox scaling. Everything is fine on the Nook HD until I put the device to sleep. When I wake the device the app is scaled incorrectly as if the bottom statusbar is not being used in the scaling calculation. So the top of my app is scaled off the screen.
If I click the recent drawer button in the bottom right and then close it, the app rescales and fixes itself. It seems this rescaling function needs to happen when the device is awakened from sleep or if it is, it needs to remember to account for the statusbar height.
Can anyone else verify this behavior on a Nook HD or perhaps even a Nook HD+?
@Joshua if you catch this topic:
Is the rescaling when the recent drawer is open/closed done by Corona or the OS?
