Default [Q] Button Click Lag

I was wondering if anyone else gets a very slight lag when pressing system buttons on TW ROMs. This is easily tested in the Settings app. Clicking any button seems to have a slight delay and the glow animation lags slightly as well. I also see it in some other apps. Is this simply a TouchWiz thing or is my performance a bit subpar? I have tried a couple different Perseus profiles and this seems to occur in all of them.

I know it's a minor issue, but I guess I'm a bit OCD when it comes to things like this .
