Half screen?

frequently since the last update, I turn my phone horizontally and I get about half the field cut off. The top half of the screen is black, I can't recenter the field and it persists when I switch back to vertical. I can scroll through the field, but can't see half of it.

Ever since updating to iOS 8 on my iPhone 5S, I've been seeing these kind of rotational problems. Clicking the home button and re-opening seems to solve it. For me, it's all apps, not just MP. The browser is the worst.

What phone/OS are you on? Do you see this for other apps as well?
