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.
