You can see it happening here -
I have heard of other people with this problem. It doesn't occur straight away either, you need to be online for a while for it to start. If you weapon swap to a non-destro weapon the stutter disappears - and reappears when you swap back. Have tried turning off various HUD items to no avail. The problem has been around for months, I just haven't bothered until now as I was happy with resto staff but now I want to use that destro ulti!
