I am on Linux though. And I can set background background through bash or
zsh escape sequences but that's not very reliable. When using ls or man
it will break in one way or the other (ls will often show patches of the
original background color, man will just use the default terminal
background color). When running an xterm I just use the `-bg` flag
which works perfectly fine (or just set up things in .Xresources file).
Is there a such a way with libvterm?

I see very similar behaviour that Lifepillar has. The background is
white or black rather than what is in `:hi Normal`.

Best regards,
Marcin
