[Q] ProBam final build error topic

Hi sorry to be a pain but I can't post in the dev forum. I'm a flashaholic and have just started with the probam KitKat end of the line build. Anyway, when I use instagram and play a video it is all in the top section all bunched up and messy looking, of the allocated square and the rest is grey. Unsure if this applies to all video playback in browsers etc. Not sure why but if someone could help in any way that'd be great. Thanks in advance.

Edit ... Sorry this is the AOSB build. Thanks. P.s. just tried YouTube and it does the same there. Please help! Thanks.
