I've just checked this in X1 and Session Drummer displays as notes there too. I perhaps wouldn't notice as 95% of my drum work is with maps and the 5% that isn't is usually solely hardware.
Perhaps it's always been that way with softsynth drums?

It doesn't appear new to X2 here anyway.
Not that helps you much though....
I still see the PRV fully zoomed out occasionally but don't have any snap issues although I have seen others mention them.
