Ah ok thank you very much, I will look into that. But this sounds like having to generate many different Metal Buffers over and over again, which sounds expensive but I guess that can be optimized? And yes you are right the many vertices are in order to get smooth curves. I will look into the GPU quadratic bezier method.

Could you clarify what you mean? Disabling Gestures did not really work for me. Imagine I am zoomed into one specific Canvas I start panning to the right edge of the canvas. After that I set the state of my Canvas Pan Gesture to .cancel to activate the Gesture of the Collection View. Now I can pan to the next Canvas. I decide now to stop panning in that direction and start panning back to the previous Canvas. Then I can't pan anymore on this canvas. Instead I still pan the CollectionView.
