I have this issue also, it seems to start with Xcode 16 for us

Of course, there's no difference but this causes the tests to fail as if there is one

Actually inspecting it more, it seems the row byte width was different, which has no visual difference but would impact the memcmp. So overwriting the snapshots seemed to fix it
