My goal was just presentation :(

No. I had a bunch of "Xorg" when launching steam which never became
anything. So I guess just a bunch of dlopen("libgl") spawing a bunch of
clients that we never used for anything more than gl[X]GetString, but
leaked the fd.

[Why does steam need 10% of the gpu to update an icon on the toolbar
which is hidden while minimised? Why do games sit in static menus at
100% gpu? Why?]
