Why does the Xiaomi 15 Ultra display uneven stripes or ripples in Gaussian blur scenarios such as entering the control center?

When you use the Xiaomi 15 Ultra to slide down the screen to enter the control center, the algorithm for layer stacking and blur processing will cause some uneven stripes or ripples in the transition, especially when there is a significant difference in the grayscale of the background. This is not a hardware issue of the phone, so please rest assured and use it.
If you would like to learn more about how this occurs, please refer to the information below:
The Gaussian blur effect is achieved through GPU rendering. If there are multiple applications running in the background, the rendering efficiency will be reduced.
You can close unnecessary background applications to free up system resources and ensure that the phone has enough processing power to smoothly render the interface effect.
