Odd screen split issue

I've just received an insurance G3, and I've noticed after immediately rooting/installing TWRP that at times, my display has a very odd/annoying offset that starts dead center. Basically at the halfway point of my display, the right half of the screen is .5mm or so higher than the left half. It doesn't always happen, but frequently it has and across multiple ROMs, despite full manual wipes in TWRP. Anyone else seen this? I'd post a screenshot, but oddly it doesn't show in screenshots.
