    Description

      I have a strange behavior on iPad (with last version 18.2.1).
      If I start my applications, after a few minutes the app crashes even if I don't do anything.
      It only happens on iPad, while on iPhone (with last version 15.8.3), Android and Windows I have no problem.
      If I start the code (created by Qt in release mode) from XCode it happens less frequently.
      The problem is on OpenGL
