This is like back when a lot of major devs like Adobe just straight up started faking window borders instead of updating their apps to the newer framework and it all looked and felt inconsistent or just obviously way off.
If this were April 1st, it might make sense. But this is a major OS release by a brand that's famous for its design aesthetic. What the actual fuck Apple? Does nobody test anything anymore? How did this get out of the lab? Who exactly is steering this ship? Tim Cook's days at the helm might be winding down.
Honestly feels like QA and release qualification are non-existent in so many organisations these days. This can't possibly be the case though, right? Right?
Brome Chrome and/or WhatsApp using their own window borders, and their stuck to the previous macOS look. They'll update them, but I wish they used the native chrome (no pun intended)
this is what I'm seeing with Safari, WhatsApp and Chrome all maximized but with various radius on each corner.
