I still run software I wrote for Linux in 1998. It runs in a LXC container with all the old libraries and it must run in an Xvnc session with a window manager of the era because there is a Qt1 widget that opens a kind of drop down menu that just doesn't work with any modern window managers. I probably wouldn't bother to try to port it to modern versions of Qt or whatnot even if I hadn't lost the source code 15y ago. So yes, it happens, it's possible, it sucks
