Hover state transition animation choppy

Hi all, I've been encountering that bug (?) on and off and it's left me scratching my head. I have attached a video showing it.

I basically just want to apply a very simple color transition (ease-out @ 0,2ms) on hover to the 'feedback' button. As demonstrated at the start of the clip, I have already done so successfully in the buttons at the top of the artboard. But the exact same hover state applied to the feedback button comes out choppy, as if another dropshadow is being briefly added only to pop out soon after. I don't understand why it's doing this as all I've done is change the background color of the button in the hover state and brought no other change.

I've done that interaction tons of times already and it worked fine up until a few updates ago. Now I've been having that bug every once in a while when trying to apply simple hover state changes. I tried dissociating my component then regrouping it then remaking it a component again; starting from brand new shapes; making a completely new one; but nope it keeps coming back.

Thanks for your help
