I created an example that shows the problem, the graphics would be different, but let's say that a sort of flame is formed that I like, it wouldn't make sense that when it is close to the sides it starts to move very quickly.

I found this example of the pig reflected in the water
howtoconstructdemos.com/create-a-reflection-with-water-effect
Where the sprite is never superimposed on the canvas, but is still on the canvas, I put the effect on the pig instead of the water and I put the camera on it by moving the objects more to the center and giving more pixels of distance for the reflection, thus creating the conditions I wanted to try, the pig never distorts the image, but when it goes out of the screen its reflection in the water speeds up anyway XD
So maybe there is no way to fix it..
