Sorry for the long delay but I have dug a little deeper on this subject. I ran the most recent stock rom and kernal and could not get the pop ups. Once I flashed a mtd rom they came back. I have not tried Enyo's newest rom to see if the pop ups and phantom menu and back button depresses. This problem occurs if the screen is spotless clean or if it's dirty with oil from your hands or what have you. I imagine someone is working on a solution at this time and would be free to test any and all solutions for devs.
