Comment 1 rust 2021-05-28 08:03:19 UTC 
vnc server: krfb
vnc client: realvnc,tigervnc,krdc

vnc client connect to libvncserver's example, `<` is map to `<`
but vnc client connect to krfb, `<` is map to `>`

[w@ww ~]$ sudo pacman -Qi krfb
Name            : krfb
Version         : 21.04.0-1
Comment 2 Merriam Webster 2023-06-02 13:03:31 UTC 
Confirm that bug still exists in default XRFB configuration

I think that issue is highly related: https://github.com/LibVNC/x11vnc/issues/115

BTW That tracker looks dead lol
