Implement KDE's workaround for GTK3/4 to support "Fitts' Law" (i.e. clicking the very top-right pixel of your screen should close a maximized window) | UPDATE: or the official GTK4 fix

[NintendoManiac64]

UPDATE: Within the last year, at long last, this has finally been fixed upstream:

• https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/8386

...but, uh, Mint doesn't even use GTK4 for anything, right?

This is most easily confirmed via the program "Archive Manager"—simply maximize its program window and try clicking on the very top-right pixel of your screen (spoiler alert: it won't work).

Note that this does not impact all programs (e.g. Nemo properly obeys "Fitts' Law").

　

Here's the 7.5-year old GTK issue on the subject that, thus far, hasn't really ever gone anywhere:

• https://gitlab.gnome.org/GNOME/gtk/-/issues/583

And the relevant KDE merge request (if it can be called a "request" anymore considering it's been merged) from just a few months ago where they discovered a work-around that could be implemented on their side of things:
