On an iOS8 device or iOS8 simulator:
I have a UITextView that becomes the first responder. Everything is fine until the application resigns (with a home key press).
After the application becomes active again, the appearance of the keyboard is mutated - see image

There is an AccessoryView keyboard on the keyboard, which I removed from the image for client privacy. However, if you remove the AccessoryView keyboard, bad behavior does not occur.
The only solution I have today is to resignFirstResponder on UIApplicationWillResignActiveNotification and become FirstResponder on UIApplicationDidBecomeActiveNotification .
Has anyone else seen this problem and [hopefully] fixed it?
For completeness, here is a screenshot of the keyboard before the application goes to Springboard
