Hi! I found a UI bug in iOS 26.0 (23A5276f). When you swipe down from the top right to open Control Center and adjust brightness using the slider, everything looks normal. However, if you long-press the brightness slider, the brightness knob detaches from the base. The button becomes smaller while the frame remains the same, making the UI asymmetrical and misaligned.
This happens consistently and is clearly a layout issue.
