KWin gets Liquid Glass effects “Only Apple” can make

Apple, back in June of this year:

This is our broadest software design update ever. Meticulously crafted by rethinking the fundamental elements that make up our software, the new design features an entirely new material called Liquid Glass. It combines the optical qualities of glass with a fluidity only Apple can achieve, as it transforms depending on your content or context.

Today, iGerman00, detailing their merge request for adding Liquid Glass effects to a KWin plugin:

Added a Concave (lens) refraction mode for a more “Liquid Glass” look, it’s a lot closer than the current implementation. Also added a Refraction Corner Radius slider (0–200px, 30 steps) to shape the SDF independently of edge size. Because the concave implementation is a bit “weaker”, I’ve raised the maxima to 30 for the relevant sliders. Added some UI logic for irrelevant options between modes.

One of the world’s wealthiest companies, outdone by a random “amateur hobbyist developer“. Not only does this merge request recreate Apple’s Liquid Glass effects, it does so with a detailed settings panel to control every aspect of the effect, something Apple obviously won’t allow you to do.

“Only Apple” my ass.
