Is it possible to disable Core Animation in SwiftUI?

I build a graphic editor. Dragging points through my canvas is smooth and fast. But when I try to display data in outline view everything slows down to 2 FPS. First I suspected slow data access, but when I check app in Instruments I found Core Animation Commits are displayed as a red blocks and Time Profiler bit busy.

Is a way to disable Core Animation for some views? Or this message is misleading?

use this modifier on the view.

.transaction { transaction in
    transaction.animation = nil
}

note that its stopped working in ios16b1. not sure if that's a bug or it was intentional.
