How much has Apple really “nerfed” Liquid Glass in the latest beta?
Here’s a comparison between iPadOS 26 developer beta 2 (first image) and beta 3.
Music tab bar:
As you can see, the “liquid” nature of it has been mostly toned down in tab bars against colored UI elements.
If I were to guess: this is still a work in progress, and they’ll land somewhere in the middle by developer beta 5 after a month of public beta.
I could also see a ‘Glass Intensity’ slider in Accessibility settings / initial setup flow.
Appealing Apps@viticci pretty much looks like Material.ultraThin that’s been around for a long while
