> Hardware limitations that were told at launch.

Sure, but still silly that even an 8 year old Dell can drive 3 monitors without issue. And clearly, the hardware CAN do it since attaching it to a DisplayLink dock and adding a driver works. Fundamentally, the GPU is capable of doing it.

    > It works fine with my old Dell FHD and my current 4k LG.

Oh it definitely works, but using Chrome on Windows, everything is super crisp on the same exact monitor whereas there is a noticeable softness on macOS

    > Different windows management model. You tab cycle through applications, and you backquote cycle through open windows. Minimized windows go to the dock.

Yeah, an inferior one. The minimized windows go to the dock and are inaccessible by keyboard. This is clearly a flaw.

    > I understand the OS not wanting to interfere much with that.

I'd argue that, you know, the purpose of the graphical user interface system in an OS in the context of UX at a very fundamental level is managing windowing.

    > I've not seen your code so I can't say much. But most people who complain about Safari really want Chrome's non-standard API to exists in Safari too. 

Works fine in Firefox and it's just using Vite PWA; really basic, standard PWA templates. Nothing special.
