The tape insulating the touchscreen circuits has to be moved over from the original, broken screen to the new screen in order to prevent the issue.
If not insulated, the digitizer makes contact with the inside of the aluminum unibody, and thus creates the grounding issue. The original digitizers are all insulated properly from the factory, but when it breaks and needs to be replaced, the replacement screens don't come with the insulating tape pre-installed. The iPad Mini suffers from a very similar grounding issue when the digitzer gets replaced. So, I went on a little investigation, because I'm actually quite familiar with problems like this. At some point, I knew for sure it wasn't simply a "software bug", because I've tried numerous kernels and ROMs, to no avail. No matter which ROM or which version of CM11S I used, the touchscreen was never quite perfect. I thought all the software did was merely filter or mask the effects of the grounding issue, and anticipated or extrapolated touches made by the user. It worked for some, and I did notice some improvement, but it just wasn't good enough for me. OnePlus has addressed this issue as a "software bug" (just like the yellow tint), and promised to fix it in future updates. See the follow-up thread to get an idea of the problems I was having. I never documented it because it just happens without warning, so I complained about it on the forums instead. Double taps turned into single taps, the camera shutter button was hard to touch, and typing was unpredictable. Some touches weren't being registered, and sometimes when I'm scrolling, something along the way would be touched instead.

Disclaimer: do not try this at home, I guess
