If that's a concern for you, there are themes for GTK3 and GTK4 that replicate classic 3D widgets and remove much of the excess padding in modern apps. https://github.com/B00merang-Project/Windows-95 https://github.com/grassmunk/Chicago95 (You should install both; Chicago95 is more actively developed, but B00merang gives you a GTK+4 theme that's currently missing from Chicago95.) Works reasonably well as a daily-driver, giving you a similar look to the modern SerenityOS GUI on a standard Linux system. Even the modern GTK+4 "responsive" apps work as designed, though with some non-critical graphical quirks.
