How do you deal with fast collisions between objects ?

I’m trying to create a pinball game.
Got my flippers going got some bumpers and most importantly a ball.
Everything is working fine but if the speed of the ball or the force applied by the flipper gets too fast or too great some issues quickly occur :

issue in question

I’ve tried everything I could find or think with my little brain :

  • change the collision detection on both the ball and the flippers
  • change settings in the mesh collider
  • added a box collider in conjunction with the mesh collider
  • replaced the mesh collider by a box collider entirely

Everytime it’s getting a little too fast something is going wrong.
Sure I could just reduce the forces applied but then my pinball would be slow and boring.

If anybody has any idea for me. It would be greatly appreciated.

Maybe this helps:
