Mine twitches a little sometimes when the AC kicks in at idle. The idle RPM fluctuates a little, too.
I seem to remember old threads about it; consensus was that it's normal, I think?
However, my old Legacy (with a similar Subaru flat 4 in it) got it worse.
It flashed dash lights and even stalled when the AC kicked in at idle.
The dealer fixed it by tickling the throttle body and resetting the ECU.
