UI very fast and "nervous" with "battery saving" ON

Hi, anytime I turn the “battery saving” mode ON, the Bliss UI gets “nervous” (the contrary of nice and smooth), especially when I open or close a folder in which I put more than one app, or when I browse the various screens of max 9 apps within a given folder.

Is anybody else experiencing similar problems? (I’m on a Galaxy S7 directly from /e/ )
