    I know that, but I thought that after these years maybe somebody might
    have a look again :)

    I have to note here that I run wsconsctl in a terminal in X. I.e. I
    open
    up my favorite terminal emulator, and just type doas wsconsctl ...

So, it happens if you change brightness outside of X11?

No. I double checked: when I switch to another VT that is not running xenocara, changing the brightness via wsconsctl is instantaneous. It only seems to happen inside of an X session.
