GoKawiiliOS 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 one setting alone goes a long way toward making the new design feel more like the previous iPhone look.
But 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 own Dylan McDonald.
Finally, we have the best of both worlds! You can now disable the Liquid Glass highlights on iOS 26.4 Beta. Definitely turning them off. https://t.co/Aj56BE1uck pic.twitter.com/ozQ6OyZaaY — Dylan (@DylanMcD8) March 9, 2026
