I run Gentoo, not Ubuntu. I have run graphical software from Ubuntu on my machine in a chroot that spoke to my X11 server in the past. I did it to get a Windows game running whose anticheat had wine support that was incompatible with newer versions of glibc than 2.32. A similar process should work with an old Linux distribution binary.
That said, you refuse to recognize that you are wrong no matter how much evidence is presented and even go so far as to present evidence debunking what you say while claiming it supports what you say. If I were to run a graphical application from the 90s on my machine, you would accuse me of making up the result. Since you will say the same thing even if I did this exercise, why should I bother?
I dare you to grab a Linux distro from the late 90s/earlier 00s and run any application that uses GTK1 or Qt1/2 on your Ubuntu 24.
Without spending insurmountable amounts of time. You will fail miserably. Your 0.0001% example is pure BS.
