This ties back to the screen being problematic/inaccurate, not the ROM. We didnt make the digitizer or the drivers

Look in the regular section (not the hacks) and you can see posts where people touch 1 part of their screen and something completely different happens. Happens even on stock phones. Someone may try to press a 9 in the dialer and the 1 lights up. Whats probably happening is your experiencing this problem, the phone registers the touch higher on the screen than what it actually is, hence, pulls down the notification bar.
Whenever it happens to me i shut off the screen, wipe it really good to clean off any oils, turn the screen back on and it doesn't happen anymore. Might have to do with oil conducting the touch on the screen to a place where your not actually touching.
