>On both Windows and macOS, windows are clearly delimited by drop shadows.

I disable window shadows with extreme prejudice because I find them visually painful. They obscure something I should be able to see without meaningfully highlighting what I want to see, which instinctively strains my eyes.

What the sincere hell was the problem with a simple, thick window border?

>Its purpose in 2024 is a visual cue.

Yes. They are practically non-existent in most environments.
