Shadcn UI Transitions Are Not Smooth (Feels Like Low FPS)

[callmedeci]

Transitions for Shadcn UI components such as Dialog and DropdownMenu do not appear smooth
Instead, animations feel choppy as if they are running at around 5–15 FPS
This happens during fade-in and fade-out transitions or similar effects

I’ve compared this with the official Shadcn UI website and their animations are much smoother and fluid
On my setup it feels laggy and unpolished
