When moving the file to the upper right corner or to the left. The viewing angle of the file changes, and the visibility of the file changes at an angle. to remove this effect, you can use containers, as Denis showed
Zoom (Focal)=10. That's what I used. Thank you.
I put an oscillation modifier on the wings to make it easier to change the oscillation frequency by points. Your modifier is a bit complicated. It's difficult to work with him in style.

On the second slide, I used containers similar to the ones Dennis had. Everything works fine.
There is one container on the first slide.
You can ignore such a shift, as can be seen in the pictures. But it is there. Everything works correctly with the additional container in the second slide.
