Demo: https://web.dahliaos.io/#home The UI is still quite slow. Hard to get excited about Flutter.

> The UI is still quite slow. Can you share your computer specs and what browser you're using? It's buttery smooth on both my Windows desktop and Mac laptop, though both are relatively new. On my 5+ year old 1.1GHz MacBook it's still entirely usable. Dragging windows around isn't entirely fluid, but it's not that bad for such an underpowered machine.

I'm on a Framework running Arch with a 165 Hz external monitor, using Firefox, and it feels sluggish to me. It's usable, but feels like the performance I'd expect from a website. For example, grabbing a window and thrashing it around, it noticeably lags behind my mouse cursor. Resizing a window from the top is pretty bumpy. It lags behind the mouse and the repainting stutters.

Please don't use or support Flutter. Its entire existence is to replace the web and force more ads to people. Do your research.

"Do your research" coupled with unsourced assertions is always an interesting argument :) As the product lead for Flutter, I can assure you that this isn't an accurate statement. The product is several years old now, and we only added ads support in the last three months, in response to customer requests ( https://github.com/flutter/flutter/issues/12114 ). Flutter is open source, welcomes non-Google contributors, and…

I think to say that its entire existence is a conspiracy to replace the web is a bit much, and I'm sure that the engineers creating it have good intentions. But that doesn't mean Google, the business, doesn't see the value to its bottom line. Google is and will always be an advertising company. Flutter may make UI development less painful for developers, but it takes control out of the users' hands. The web is great, despite painful UI development, because as a user I can adjust it to my liking, namely remove advertisements, tracking, and other annoyances.

AMP was supposed to speed up the web for mobile users. I'm sure the engineers that worked on AMP believed they were doing that too.

Design language looks very similar to Windows 11? Not sure if it was intentional since it must have been in development for a while. Anyways, it’s a very elegant looking environment.

Reminds me of Ubuntu Unity personally, haha

Nice, already better than Gnome!

Personally, I think GNOME has more polish than this—the margins are correct in GNOME applications (eg. in the "Search settings" text box in the Settings application). GNOME typically doesn't have those kinds of issues.

Gnome is a UX mess, everything is huge, zoomed, desktop screens have more WIDTH then HEIGHT, and yet they waste a shit ton of HEIGHT and force us to constantly have to scroll to see more content

Not even macOS went this far, Apple made the right call to develop a separate ipadOS, specific for touch screen UXs

Gnome sure is a polished tablet OS mess

On both my Windows laptop (Ryzen 7 + 1080Ti) and Windows Desktop (Ryzen 9 + dual RX 5700 XT) machines, it is really slow. Dragging windows is unbearable and the other apps are quite laggy (such as switching views in the "media" app). Both have hardware acceleration enabled.

Certainly Google sees value in Flutter, otherwise we wouldn’t fund it to the tune of 100+ engineers. But our motivations are less malevolent than you might assume. Here is our strategy doc, which we publish in the open (not many products can say that, I think): https://medium.com/flutter/flutter-in-2022-strategy-and-road...

Perhaps we have different ideas of what constitutes "buttery smooth". I find the performance usable but sluggish. I think many people have become accustomed to this kind of performance though. Regardless, I find the design of the UI quite appealing. AMD® Ryzen 9 5950x, 32 GB RAM, Linux/Fedora 35, Firefox 97.0, Chromium 96.0.4664.110

> AMD® Ryzen 9 5950x, 32 GB RAM, Linux/Fedora 35, Firefox 97.0, Chromium 96.0.4664.110 Same CPU in my Windows workstation and it's plenty smooth. Not just usable, but smooth. This is at 4K. Do you have a modern GPU, or something quite old? Or do you have browser hardware acceleration disabled? If not for your GPU, it's also possible that Linux simply performs significantly worse than Windows for whatever reason.

Yes, I have a recent and powerful GPU with hardware acceleration enabled. I also tried this on my Windows box (i7-9700k, Nvidia GTX 1070), and if anything, it performs a little worse than my Linux box. It's definitely usable. I just have a low tolerance for sluggish software.

Just another data point here: I'm running a relatively high-end workstation on Linux/Fedora 36, and it is quite smooth in Chrome but somewhat sluggish in Firefox.
