Landscape display glitches topic

Hey guys I have another strange problem on my n6. It seems that when I am in an app landscape half of the screen (bottom) turns black and sometimes flashes what it's supposed to be and will go back again. Scrolling makes it worse but I can tap through the black portion and highlight text and it will temporarily go away. It almost looks that the keyboard is trying to pop up but I've switched my keyboard and I can reproduce it in multiple apps
