Configuration

-- Pull in the wezterm API

local wezterm = require 'wezterm'
local mux = wezterm.mux

    local tab, pane, window = mux.spawn_window({})
    window:gui_window():maximize()
end)

local config = {}

-- In newer versions of wezterm, use the config_builder which will

Running wezterm -n --config 'window_background_opacity = 0.3' --config 'macos_window_background_blur = 20' and then using the https://wezfurlong.org/wezterm/config/lua/keyassignment/ToggleFullScreen.html assignment (default is Alt-Enter) works just fine for me with the default non-native fullscreen mode.

However, if you click the green macos native full screen mode "traffic light" button on the title bar, macos will use native full screen mode, which will counteract the transparency effect. I don't think I have any control over that, so the resolution is: don't do that!

Just noting for anyone stumbling across this, you can somewhat work around it by first creating a new desktop in Mission Control, then moving WezTerm over to that desktop and running the ToggleFullScreen mentioned above.
