At a high level, my app’s view hierarchy is a UISplitViewController, where the secondary column contains a UITabBarController that contains several UINavigationControllers. With this particular setup, I’m noticing every time a view controller is pushed, the navigation bar animation glitches. Notice how the back button and navigation title slightly slide left on each push, before abruptly resetting their positions. This issue only occurs when Liquid Glass is enabled. The issue does not occur if the UIDesignRequiresCompatibility key is added with a value of YES. I assume this is a UIKit bug, so I’ve filed FB20751418. But wondering if anyone is aware of any workarounds in the meantime as this animation glitch is quite distracting.

Is it not possible to change the background color of popovers in iOS 26? The backgroundColor property of UIPopoverPresentationController seems to just get ignored when Liquid Glass is enabled. Here’s a minimal repro: let presentedVC = UIViewController() presentedVC.modalPresentationStyle = .popover presentedVC.view.backgroundColor = .clear let popover = presentedVC.popoverPresentationController popover?.sourceItem = button popover?.backgroundColor = .red present(presentedVC, animated: true) If the UIDesignRequiresCompatibility key is set to YES, then the popover background color works as expected.
