Solved it, I spent a long time looking for a solution. Because I need to switch between transparent and opaque navigation, I used the navigationbar extension. I used the one written by this master: https://github.com/ltebean/LT..., so the problem was solved after the update.

Same problem encountered
Usually it only appears when you customize the navigationBar. Is there any code?
