Even without the rounded corners it was more difficult than it needed to be. The corner resize should take up way more of the sides of the window. If my mouse is 90% of the way to the corner, what are the odds that I want to resize the window only horizontally or vertically?

The Apple hiring process maybe needs even more tests to find an engineer who can just fix this sensibly. That must be it.

Tahoe is the most frustrating daily driver I've endured in decades.

it isnt perfect, but with BetterTouchTool you can toggle resizing -- e.g. three finger double tap on a trackpad, move your cursor around to resize, double tap again to exit the mode.

I use Yabai, which is pretty good -- and you don't have to completely disable SIP.

For moving windows around (floating if using Yabai), I just hold HYPER and move my cursor around (Start Moving Windows). Release HYPER and it stops.

Oh, this is probably related to why I cannot resize "live caption" windows at all on the latest version of MacOS. They have been mucking around with resizing and not testing it well.

Half the time my Mac doesn't show the resize cursor when in regions where it works to resize windows. It's annoying. But not quite the same issue as seen here.

Let's just go back to Macintosh OS 9 ... I LOVED OS 9!

well this certainly goes a long way to explaining why i've been fighting with window resize on tahoe :p

it's stupidly difficult to grab windows by the flat edges, too

It is quite possible the proposed improvement was not implemented because it wasn’t good enough. Fingers crossed for the next version.
