iOS 26.4’s new setting lets you disable another Liquid Glass effect

iOS 26.4 beta 4 arrived today, and with it a new Reduce Bright Effects setting that lets you disable various flashing elements common in Liquid Glass.

‘Reduce Bright Effects’ is a new UI setting in iOS 26.4

iOS 26’s Liquid Glass design has seen several refinements over time, but also new settings for dialing it back.

Most prominently, iOS 26.1 added an option in the Display & Brightness settings to switch from the default Clear design to a more iOS 18‑like Tinted look. That setting alone goes a long way toward making the new design feel more like the previous iPhone look.

In iOS 26.4, there’s another new setting that lets you disable a different aspect of Liquid Glass. It’s called Reduce Bright Effects, and it controls the bright flashing response that shows up when interacting with certain UI elements. You can see a comparison in the X post below via 9to5Mac’s Dylan McDonald.

To enable the Reduce Bright Effects toggle, go to Settings → Accessibility → Display & Text Size. Combine this with the previously available Tinted Liquid Glass option for a look that’s even closer to the pre‑iOS 26 design.
