My 09 Forester X Premium 5-speed manual does the same exact thing. And the transition from off throttle to on throttle is practically impossible to modulate smoothly.
 
Does anybody know the fix?
 
Does it have anything to do with a too hot thermostat? It acts like it's running hot, but I can't tell because it has no guage. When it's still warming up, not totally up to full temp but not cold, it runs perfectly.

Took my Forester in again and they reprogrammed the ECU with an update and problem solved!

Glad to hear it.
 
I was going to ask if yours is a PZEV, but it's a moot point now. PZEV will drop revs slowly for emissions purposes, but what you describe did not sound normal anyway.
