When you pull down the notification or Control Center on the Xiaomi 15T Pro, the system applies a Gaussian blur effect to create a translucent appearance. If the wallpaper contains high-contrast or uneven grayscale areas, overlapping layers during the blur process may cause visible stripes, ripples, or banding.
This phenomenon is a normal algorithmic effect of Gaussian blur rendering and not a hardware issue. It occurs when the blur filter blends background pixels with different brightness levels, creating minor visual artifacts in certain conditions.
The device continues to perform normally, and this effect does not impact usability or display quality. Xiaomi engineers are optimizing the blur algorithm to improve transition smoothness and minimize such occurrences in future updates.
