A Wired writer trialled a new "more clear" slider in Apple's iOS 27 public beta, which allows users to make the Liquid Glass interface even more transparent than its default setting. Liquid Glass, Apple's translucent design overhaul, proved divisive when it launched in 2025, with critics citing poor text legibility, prompting Apple to make the effect more opaque in subsequent updates; the new slider now lets users choose their preferred level of transparency rather than having it fixed.

The public beta for iOS 27 arrived in mid-July, with the full release expected in September, and the transparency control sits under Settings, Appearance, Liquid Glass, alongside existing Reduce Transparency and Increase Contrast options. The writer set the slider to maximum clarity for a week, describing warped icons, refracting text and an added sense of depth reminiscent of the parallax "3D apps" effect Apple introduced with iOS 7 over a decade ago. By the midpoint of the test, the heightened transparency had come to feel normal, suggesting users adapt quickly to the more extreme visual style.
