I have the same issue.

That's the CapCut app (found by reverse image search).

This is also happening to us (macOS menu bar extension app). Even our customers (downloaded the app via App Store) report this problem after updating their app on macOS to a new version, which is a bigger issue, as not only developers / TestFlight users are experiencing this but paying users. Who else is having this problem and who has a fix for it? Telling people to restart their computer is a bad customer experience...

I am also struggling with this issue. I created FB13286723. As this exists since iOS 15 up to iOS 17 and is even present when opening and annotating a PDF from e.g. the Apple Files app (open a PDF from there, activate annotation mode, zoom in, draw => blurry) I have not much hope that Apple will address this 😭 If anyone found a workaround, please share.

I have a similar problem but I'm using a UIViewControllerRepresentable, UIViewController and a UIHostingController in my (otherwise SwiftUI)-view hierarchy, which is rendered with the same yellow/red "no entry" sign. I don't know yet which of these UIKit-brigdes causes the issue, but I guess MapKit in SwiftUI uses a similar brigde under the hood, so maybe it's related.

Did you manage to make it work? If yes, can you upload your code to GitHub, I would be interested.

I'm getting the same problem here (running 14.7.1). Did you find a solution yet? It appears to crash whenever a node is rendered. I made sure to only add nodes in the delegate callback func renderer(_ renderer: SCNSceneRenderer, updateAtTime time: TimeInterval), but to no avail. I tried running iOS 15.0 beta 6 and there it works, so I guess, something broke in iOS 14.7.*? Any hint or workaround would be appreciated.
