I'm coming from CM 10.1 and I recently flashed to the 4.4.4-20140706 Nightly for the Oppo find 5 and I noticed there was a jerkiness in the middle of the screen and being unresponsive. You can see it here (I can't post links yet but it's in the very middle and even an icon couldn't fit in it.). In between the spotify and drive icon. The space between them doesn't work. So I thought it was my screen doing it but the problem is there is no damage to my phone so I flashed back to CM 10.1 and it worked perfectly.
Another issue is when I tap the screen sometimes it turns it on which randomly turns it on in my pocket. is this a setting that I can turn off?
