Question Erratic touchscreen behavior while plugged in, in KitKat OTA

I just installed the OTA (183.46.10.XT907), and have been playing around with it a little while it recharges. I've noticed that my touches weren't doing what I intended at all, so I investigated.

This is with the phone plugged in ...



... and with it not.



Sometimes, the difference is more drastic, but those are hard to get screenshots of. Is this affecting anyone else?
