This one really bothers me. Whenever I maximize or tile windows (which is all the time), I see multiple layers of oddly rounded corners.

I think if there's any upside to Tahoe, it's that it might push me into blogging for the first time in my life ever, because I just can't keep things to myself.

I actually feel sorry for Apple's developers. I can't see how you can ship software so bad and inconsistent unless you've been handed a terrible design spec from Dye's team.

There is so much of that in modern apple. Clear issues caused by a seemingly bright idea, but the idea still pushed forward no matter what.

One example that I hate on iOS: the notification/lockscreen curtain is supposed to cover the content as it slides down. That’s what a curtain does, this has been the language for years. Now the curtain is transparent, so it can’t cover the content behind. How does the content disappear then, as you slide the curtain down?

… it doesn’t. Icons do a buggy looking animation crashing toward the user and through the screen, and if it’s an app there is just no transition. You can check by sliding the curtain down slowly and then letting go.

"Clear issues caused by a seemingly bright idea, but the idea still pushed forward no matter what." .. well put. It occurs to me that this is the case on the HW front with Apple as well. I remember the butterfly keyboard, the notch, everything glued in and unservicable, the removal of ports like magsafe, ethernet, USB-A... well, at least some of the HW mis-steps have been reversed. We see some movement in that direction from the later versions of Tahoe.

> seemingly bright idea

i disagree about that one.

im not a UX expert by any means but my first impression at WWDC seeing liquid glass was "holy shit, they pulled that off? i know apple would never compromise on legibility, so... how? there are so many situations where this won't work, and they can't exactly control the content that the buttons are overlaid on top of"

cue my confusion when it was exactly that: an obviously problematic idea implemented with all the obvious flaws showing up

they have largely fixed it now, half a year later, but the liquid glass isn't very liquid anymore. it's frosted. which is fine, but obviously not the original idea they were going for

contrasty backgrounds are fundamentally incompatible with legibility

That's what I mean, even if worded badly. Someone probably managed the glass distortion effects as an experiment, or demoed a transparent redesign of a small portion of the UI, and it looked awesome. I think it's cool that they can green light weird ideas, otherwise there's stagnation. But it is obvious that there were fundamental unresolved issues, and yet something in the process pushed the idea forward anyway.

It signals something very wrong in company structure. If you can't trust the process to drop what doesn't work, then trying new things is risky. And as you say, it's an experiment that feels so unlike apple, to disregard polish and accessibility that way.

Re:macOS Tahoe windows have different corner radiuses by chilmers on Tuesday March 10, 2026 @07:25AM (#47321769)
I think a primary concern when Apple evolves their new design language nowadays is competitive differentiation. Because so many people try to clone their UI, they seek to add visual elements like frosting, glass, squircles, etc. that are difficult or impossible to achieve in competing platforms. Gradually others catch up and they need to evolve it again. Liquid Glass seems like an aesthetic choice made purely for the technical difficulty of the simulated physics necessary to accurately recreate it.
Re:macOS Tahoe windows have different corner radiuses by jlnthws on Tuesday March 10, 2026 @08:12AM (#47322161)
Wouldn't that imply that design is solved (at least regarding visual elements discussed here)? Then why not move onto other things? Why self-sabotage their success?

Re:macOS Tahoe windows have different corner radiuses by ryandrake on Tuesday March 10, 2026 @10:50AM (#47324052)
A lot of bad, unwanted features get written purely because "developers need something to do" and the same thing happens on the design side. I spent over a decade as a developer at various companies fighting bored designers who just had to redesign the look and feel of the app over and over because the current one was "stale" and "lacked pizzazz and pop!" But, then we devs would do the same thing to the feature list, refactoring and reimplementing and adding features for the sake of writing software, so... I was a hypocrite to complain.

Re:macOS Tahoe windows have different corner radiuses by threatofrain on Tuesday March 10, 2026 @05:16AM (#47320814)
If AR/VR took off then something along the lines of liquid glass would be the only option for the entire design space. Early on there's going to be a lot of embedding of app context into the AR/VR setting to get a jump-start on content. But if people are going to be walking around with rectangular panes around their head, it's better that part of the app chrome is transparent.

Is this compromising readability? Yes, but now there's another kind of perception problem, and it's whether you can see what's literally in front of your eyes in physical space.

Re:macOS Tahoe windows have different corner radiuses by kace91 on Tuesday March 10, 2026 @06:12AM (#47321256)
The AR push is also an issue in itself. There are very fundamental issues that remain unresolved, and I would say untackled even.

VR setups make you isolated and vulnerable. Any VR device is really awkward to use in public (read: in your living room or in an office).

In turn, AR setups that let the world through reduce image quality by virtue of being transparent, and it is unclear that they provide advantages. You get a slightly more immediate access to notifications in return for permanently pointing a camera towards anything you look at, which is understandably not well received.

And that's just for content consumption. When you introduce work, input is still significantly worse unless you're sitting in front of a keyboard and mouse, in which case you might as well have a full laptop.

Kinda-not-really? Wayland has wl_region objects and wl_surface_set_input_region but wl_region only has axis-aligned rectangles. you'd end up approximating the circle (or whatever shape) as a union of horizontal rect slices, rather than a pixmap. you can't just hand over a pixmap mask, you have to decompose the shape into rects yourself.

    ... liquid glass isn't very liquid anymore. it's frosted.
is an important point. Liquid Glass does not come across as "a bold design idea which is slightly flawed" but rather something which failed so bad when they tried it that they dialed the intensity back to the point where it doesn't make a statement anymore. So it looks like they hired an intern to randomly add anti-antialiasing here and there for no good reason.
Re:macOS Tahoe windows have different corner radiuses by philistine on Tuesday March 10, 2026 @12:43PM (#47325690)
If they had simply put the clear glass on top of a heavily frosted shelf, maintaining a clear divide between content and control and making sure the clear glass was never directly on content, we would be discussing the ways to improve the design instead of everybody's dismissal of the whole thing.
Re:macOS Tahoe windows have different corner radiuses by merlindru on Tuesday March 10, 2026 @03:26PM (#47327747)
they are doing exactly that now, but at some point, there's no discernible difference between a gaussian blur and a complex shader like liquid glass.

taken to an extreme, the heaviest possible blur results in just one solid color (at which point there is no visible difference between a gaussian blur and LG at all).

so the more blurry the shelf is, the less important liquid glass gets. therein lies the dilemma: you can't have interesting, complex backgrounds AND legibility. it's either one or the other.

the current design is good. or becoming good, finally. but it's also not worth the, what, 2 hour reduction in battery usage, the lags and visual glitches, the major changes many apps see themselves forced to undergo, ... because it looks almost like a gaussian blur now.

Re:macOS Tahoe windows have different corner radiuses by s3p on Tuesday March 10, 2026 @05:51AM (#47321077)
This one has always confused me. And then, to be even more confusing, if you start sliding up slowly, the background does not disappear. It stays this time around. Pull down slowly, no background, just the glass effect. Pull up slowly, still have the background, no glass effect. I guess I don't necessarily hate it, it's more of a neutral thing, but who is deciding these strange things??

Probably nobody, just some artifact of the overlay APIs used default behavior that they didn't bother to streamline.

Because we fucking have to see it every day. And the sloppiness compounds and is indicative of further rot.

Of course the different radii also means different code paths were used, which points to a mess of APIs and frameworks underneath too.

And that's before we add the usability issues (like hard to read labels due to the glass effect and such, or bizare dragging boundaries, etc).

>Doesn't that seem a bit... particular?

Good software is about being particular.

If we wanted any random crap, we'd use any random crap.

The number of times auto update of some app has caused the thought process “but that wasn’t like that yesterday… or was it… hm… oh it was an update”. Just minor things, small mostly unnoticeable if don’t have an “eye for details”.

I don't have OCD, but easily notice inconsistencies in various design choices these mega-corporations continue to fumble.

It's less "OMG I can't focus on coding because Calculator and TextEdit aren't sharing the same border radius" but more "The UX/UI department seems like they're on perpetual vacation if Apple is letting simple things like this slip through", and this specific case is just an example, every version of macOS seems to get worse when it comes to consistency.

You don’t need to care, but for the ones who do, Apple was one of the few vendors one could identify with. Attention to detail and craftsmanship was their motto.
Re:macOS Tahoe windows have different corner radiuses by steve1977 on Tuesday March 10, 2026 @08:45AM (#47322517)
It's the lack of attention to detail, from a company who once was famous for its attention to detail.

And it seems they're lacking in many corners (scnr...)

Re:macOS Tahoe windows have different corner radiuses by robertoandred on Tuesday March 10, 2026 @09:46AM (#47323199)
It’s actually the opposite. The corner radii are defined by the window type and the concentricity of its elements.

People who lack attention to detail just think things are randomly different.

Re:macOS Tahoe windows have different corner radiuses by steve1977 on Tuesday March 10, 2026 @01:59PM (#47326665)
I think I know what you (and Apple) mean, but it doesn't make sense IMHO.

Because then, in apps without a toolbar, like Terminal, the window corner is concentric with the close button and has a smaller radius.

In apps with a toolbar, it still concentric with the close button, but has a larger radius. Because it probably also tries to be concentric with and accommodate toolbar items on the right-hand side.

But then, why not just keep the larger radius for both window types, so they are consistent? It wouldn't break concentricity and you wouldn't have non-matching corners, especially a the bottom, where there's usually few or no elements to be concentric with anyway.

That's exactly the kind of detail I'm talking about. There is a nice idea behind it, but it has not been thought through IMHO.

Personally it's the fact they introduced such an extreme and opinionated UI design change, but then couldn't be bothered to roll it out consistently. The old window radii were fine. Sequoia looked good. The OS felt good as a whole. Then we get an update where you have a very opinionated theme forced on you in a half-assed fashion. If you could just disable it, return to classic radii, it'd be a nothing burger and Apple would roll it back if enough people disabled it.

But that's not how apple works.

Does it matter if it's 3rd party apps or not? Wasn't a huge part of the sell with Apple's own GUI toolkits that all native apps work uniquely, but look familiar and like part of one and the same? The consistency and "all apps look and work great" I seem to recall being one of the "features" people used to tout about OSX.

FWIW; TFA compares the border radius of TextEdit and Calculator, both two Apple apps, built-in nonetheless.

The thing which killed me is this is one of the things Windows 10 got _right_ (well, took the path of least resistance) with square corners which made screen grabs look good/work more easily --- I run a utility to get them back in Windows 11 (and have seriously contemplated investigating if removing the glass from my laptop screen and scraping away the paint which obscures the corners is an option to get those pixels back....)

Used to be this sort of thing "just worked" on Mac OS --- you'd think with a diminishing number of UI tool kits/dev tools this sort of thing would get better/more consistent.... always liked "Themes" and this just gives me one more reason to wish that they would come back.

Assuming the corner radius scales with the size of the window, there is an argument to be made (I won't sign onto it) that the different corners actually give you additional useful information about which window each belongs to, helping you select the right one.
