Is your target mostly shades for black and grey ? My 7D on AI is trying to focus when I target my roccat kave headphones.. its color is shades of black to grey. When The target is contrasty like the text in this reply box or a white remote with black buttons.. It don't hunt for focus or"stutter " like yours. Even my 60D does the exact same thing. Tho seems to not hunt that much on the headphones.

Also if your target is moving even slightly it will change focus..

But if its static and contrasty maybe the light  is affecting the focus sensor. As electrical lights has 50Hz or 60hz depending on what country your in ?
