Flicker on first show

[yellow8-vom]

I show FloatingNotificationBanner like this (cfr code)
The first time a banner is shown, there is a flicker.
Happens on iOS 17 & 18 (I don't know for earlier versions of iOS).
I use the latest version of this package.
I tried this partially related solution, without success: #424

static func showSuccessBanner(title: String, subtitle: String) {
    DispatchQueue.main.async {
        let banner = FloatingNotificationBanner(title: title,
                                                subtitle: subtitle,
                                                titleFont: UIFont.systemFont(ofSize: 14.0, weight: .semibold),
                                                subtitleFont: UIFont.systemFont(ofSize: 12.0),
                                                style: .success
        )
        banner.backgroundColor = .systemGreen
        banner.haptic = .none
        // Show the banner
        banner.show(cornerRadius: 12.0)
    }        
}

Am I doing something wrong? It did not happen before (this issue started quite a long time ago, but before there was no issue).

Am I the only one encountering this issue?
