Annoying volume slider issue

I have the AT&T variant. My volume slider is very choppy and laggy, when trying to adjust volume incrementally. It's not a big deal, but it is extremely annoying! Does anyone else have this issue? I'm rooted, all bloat gone, Greenified, etc. Had the issue from day one. I did do a factory reset the day I bought it. It's never presented any differently, regardless.

Any help would be appreciated. Thanks!!
