NavigationBar Jumping Problem

Hi guys, first of all, thanks for creating such a great UI library. I enjoy using this framework.
Recently, I saw a problem about when navigation back through the back button. The navigation bar is jumping when back button pressed. My code is not customized, it s from sample project. Can you help me to solve jumping?

Main NavigationController code is below;

class AppNavigationController: NavigationController {
open override func prepare() {
super.prepare()
isMotionEnabled = true
guard let v = navigationBar as? NavigationBar else {
return
}

v.backgroundColor = .white
v.depthPreset = .none
v.dividerColor = Color.grey.lighten2
}

override var preferredStatusBarStyle: UIStatusBarStyle{
if #available(iOS 13.0, *) {
return .darkContent
} else {
return .default
}
}
}

These are the root ListViewController UI lifecycle functions. Nothing is special.

override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
}

override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
}
