Same issue here...

I solved rolling back to Xcode 13.2 , hope a new version of Xcode (13.3.x) will fix this..

Same problem here, our mission planning app (with MKpolylines on the map) now get non-responsive with iOS16.1 while editing the mission. Anyone found a solution that is not changing mapstyle?

same problem, have you found a solution?

To workaround I've reduced the number of polylines, from about a hundred to less than 5, but now I can't color each segment as desired... But, in my case, better user experience than map flickering Using the 3D map style I have gave me less problems (or no problems) but that style is not good for my app I wonder if apple is aware of the problem, until iOS 16.0 everything was fine
