@nikitonsky It went away when people stopped using Super Panavision 70 https://en.wikipedia.org/wiki/Super_Panavision_70

A lot of care was taken to get it right when filming Lawrence of Arabia e.g. from IMDB
"To film Omar Sharif's entrance through a mirage, Freddie Young used a special 482mm lens from Panavision. Panavision still has this lens, and it is known among cinematographers as the "David Lean lens". It was created specifically for this shot and has not been used since.”
