Funny this thread pops back up when I experience this for the first time a couple of nights ago. I can confirm this does in fact happen. I never even bothered taking the OEM charger out of the box because I was using an old Moto charger I had laying around. That particular charger started giving me problems so I grabbed the first USB charger I could find(I've accumulated quite a few over the years) and noticed my screen could hardly register a touch when connected. I immediately noticed it since I have the slide2unlock app, and was unable to get my screen to register a touch, and slide.
Anyway, I have been suffiicently scared straight, so I'm currently using the OEM.
