The latest v9 should fix that… at least the lag when browsing. It was previously loading summaries at the same time as cast which slowed it down but in v9.0.29 it loads summary separately which kicks in faster now. It was a major irritation for me so I notice it being fixed. 
I really wish they’d compress some of the “comfortable” spacing to “cozy” spacing. On Home and on TV episodes it’s only 2 lines. NewExp Feedback: Display More Summary Info
I actually liked the zoom on background image when going to details, just not the color overlay being a bit too opaque. I’ll live either way.
