When you click "Settings-General-Production Team", a rolling animation will be played for you, and there will be a gradual dark effect around your screen. However, when the rolling animation is played on the 1.21.60 mobile terminal, the gradual black hole effect around your screen disappears and becomes a blank picture, which has not been found on the mobile terminal beta and windows computer terminal for the time being, and may only be a screen display error that occurred on the mobile terminal 1.21.60.
Normal situation: When playing scrolling text animation, your screen should be surrounded by a gradual dark effect, not a direct blank.
Supplement: This problem still exists in patch versions 1.21.70 and 1.21.71.
How to reproduce the problem: Open the settings, click General, and click "Production Team" to reproduce the above problems.
Expected situation: After clicking "Production Team", your screen should be surrounded by a gradual dark effect, instead of disappearing directly as in the picture.
