If you're a fan of Microsoft Edge because of its simplistic design that adheres to Microsoft's own design guidelines, the latest release is going to disappoint you. As of Microsoft Edge version 138, the "enable Windows 11 visuals" setting is no longer functional, meaning all of the blur effects that were introduced specifically for Windows 11 are no longer present.

This makes the browser much uglier than it was before, and it looks broken as a result. The rest of the Windows 11 interface still support translucent blur effects, including first-party apps like the File Explorer, Notepad, and the general OS interface. Microsoft Edge is now missing out on this crucial design aesthetic, making it stick out like a sore thumb and appear unfinished.

The acrylic and mica blur effects used to be present in the Microsoft Edge title bar and context menus. It was a subtle but very important design addition that helped aligned the app with the rest of the Windows 11 interface, and generally made it look a lot nicer. But with the blur effects seemingly broken with version 138, the whole browser just looks worse as a result.
