If we're talking a simple "hello world" window then sure, you can resize that at 60fps on pretty much any system.

But most nontrivial apps can't re-layout at 60fps (or 30fps even).

They either solve it by (A) allowing the window to resize faster than the content, leaving coloured bars when enlarging [electron], or (B) stuttering or dropping frames when resizing.

A pleasant exception to this I've noticed is GTK4/Adwaita on GNOME. Nautilus, for me at least, resizes at 60fps, even when in a folder of thumbnails.

On the Mac side, AppKit, especially with manual `layoutSubviews` math easily hits 60fps too. Yes it was more complex, but you had to do it and it was FAST.
