Error: [LSAGLView] attempt to use deleted framebuff

Recently, we detected an issue that is freezing the CameraKit Preview.

We are using SwiftUI.

It happens in strange cases.
Cases we detected:

  • Having the PreviewView in a View if we open an overlay or a fullScreenCover > Freezes (does not happen with all of them)
  • Starting opening the Control Center > Freezes (but only the first time the app is running. If we move back and start again without restarting the app, everything works fine)
  • Receiving a System Alert (Photo Library Permission, Low Battery) > Freezes

On Xcode, we can see that this error is logged in the console every time the Camera freezes.

I already saw another user complaining about this, but it seemed that was while he was configuring his project.

    We found out the problem on our side.

    We had the NavigationLink that was handling the View with the Camera Preview inside a ScrollViewReader, and the ScrollViewReader was interfering with the Camera Preview update.
