Touch issues (not screen only)

So on various android devices with capacitive buttons over the years, mostly Samsung, I've always had an issue fat fingering the capacitive buttons. OPO seems to be no different. I'm running the latest CM nightly and its been driving me crazy. What i mean is ill be doing something on the screen close to the bottom edge and accidentally hit one of the capacitive buttons. I know the obvious answer is to switch to on screen buttons. I am currently using the on screen buttons while I wait for a CM build I think will fix my issue to finish, but I've noticed something else. Switching to on screen buttons seems to really help with touchscreen issues.

So my questions are A) does anyone else "accidentally" hit the capacitive buttons while using their OPO like all the time, and B) has anyone else noticed using the on screen buttons helps with touch issues? Or appears to at least.
