Maybe is related to this

I don't know what is your use case, but it is never a good idea to heavily
delete and recreate sprites (Yes, I known your code is a bugdemo, but your
real code must be deleting and creating something also, otherwise you had
not noticed the issue)
It is better to preload the images and then change the image member of
sprite.
An animation example for this can be seen at
