Configuration

Issue occurs with no config as well

-- Pull in the wezterm API
local wezterm = require 'wezterm'

-- This will hold the configuration.
local config = wezterm.config_builder()

-- This is where you actually apply your config choices

-- Colour Scheme
config.force_reverse_video_cursor = true
local function get_appearance()
  if wezterm.gui then
    return wezterm.gui.get_appearance()
  end
  return 'Dark'
end

local function scheme_for_appearance(appearance)
  if appearance:find 'Dark' then
    return 'tokyonight_night'
  else
    return 'tokyonight_day'
  end
end

config.color_scheme = scheme_for_appearance(get_appearance())

config.window_background_opacity = 0.7
config.win32_system_backdrop = 'Acrylic'

-- Font
config.font = wezterm.font_with_fallback {

    bottom = 0,
}

    -- },

    -- {
    --     label = 'Ubuntu',

If you try commenting out one or the other (or both) of these lines, does it get better?

config.window_background_opacity = 0.7
config.win32_system_backdrop = 'Acrylic'

[keanesc]

Yes commenting either line seems to fix it. It is only when both are uncommented and the terminal is restarted that the artifacts reappear.

Sounds like an issue with your graphics drivers, as those options don't change the way that wezterm directly works, they just set flags for your OS compositor.
